Kubernetes is open-source software that allows you to deploy and manage containerized applications at scale. Kubernetes can manage clusters on Amazon EC2 instances, run containers on those instances, and perform deployment, maintenance, and scaling tasks.

Kubernetes enables using the same set of tools to run containerized applications on-premises and in the cloud.

AWS provides Amazon Elastic Kubernetes Service (EKS), a managed, certified Kubernetes-compatible service with community-supported service integrations for running Kubernetes on AWS and on-premises.

Kubernetes is a project that is open source. Kubernetes enables you to run containerized applications wherever you want without changing your operational tools. Kubernetes is regularly maintained and improved by a large community of volunteers.

Kubernetes’ large community creates and maintains Kubernetes-compatible software that can be used to enhance and extend application architectures.

Kubernetes Security Best Practices on AWS

Understanding the Model of Shared Responsibility

When using managed services such as EKS, security and compliance are viewed as shared responsibilities. In general, AWS is responsible for “inside” cloud security, and the cloud customer is responsible for “inside” cloud security.

AWS manages the Kubernetes control plane through EKS. This includes the Kubernetes master server, the etcd database, and any other infrastructure that AWS requires to provide secure and reliable services.

Identity and access management (IAM), pod security, runtime security, and network security are primarily the responsibility of EKS customers.

AWS is also in charge of keeping Kubernetes patch releases and security patches up to date for EKS-optimised Amazon Machine Images (AMIs). Customers who use managed node groups (MNGs) must upgrade their node groups to the most recent AMI using the EKS API, CLI, Cloudformation, or the AWS console.

Red/Blue Team and Penetration Testing Practice

Divide the security personnel into two groups: red and blue. The red team investigates vulnerabilities in various systems, while the blue team handles vulnerability defence.

If you need more security personnel to form a separate team, consider hiring a third-party organization familiar with Kubernetes exploits.

Kubesploit is a penetration testing framework for conducting tests. It can simulate real-world attacks on Kubernetes clusters, allowing the blue team to practise responding to them and assess their effectiveness. You can attack your cluster regularly to find vulnerabilities and misconfigurations.

Auditing and Logging

Audit log collection and analysis can be beneficial for a variety of reasons.

Logs are useful for determining the root cause of production issues. When a sufficient number of logs are collected, they can also be used to detect abnormal behaviour. EKS transmits audit logs to Amazon Cloudwatch.

The EKS-managed Kubernetes control plane manages audit logs. Amazon provides instructions for enabling and disabling control plane logs for Kubernetes API servers, controller managers, and schedulers.

Scan Images for Vulnerabilities Regularly

Container images, like virtual machines, can contain vulnerable binaries and application libraries. The best way to avoid threats is to scan images regularly with an automated scanner.

Images in the Amazon Elastic Container Registry (ECR) can be scanned automatically or on demand (every 24 hours). Clair, an open-source image scanning solution, is currently used by ECR.

The results of the scan are written to EventBridge’s ECR event stream. The scan results can also be viewed in the ECR console. Vulnerabilities rated as HIGH or CRITICAL should be deleted or rebuilt. When an image that has been deployed becomes vulnerable, it should be replaced as soon as possible.

Network Governance

Pod-to-pod communication is enabled by default in a Kubernetes cluster. Although this flexibility is beneficial during development, it is not considered safe for production.

Kubernetes network policies allow you to limit network traffic between pods as well as between pods and external services. Kubernetes network policies cover layers 3 and 4 of the OSI model.

Network policies identify the source and destination pods using pod selectors and labels, but they can also include IP addresses, port numbers, protocol numbers, or a combination of these.

Key Takeaways:

These are some key takeaways on the basics of Kubernetes deployment and how to secure it on AWS:

➔     Understanding the shared responsibility model—When using managed services like EKS, security and compliance are considered shared responsibilities.

➔     Practise red/blue team and penetration testing—the red team investigates vulnerabilities in various systems, while the blue team defends against them.

➔     Auditing and logging—collecting and analyzing audit logs can help determine the root cause of production issues.

➔     At-rest encryption—Kubernetes provides three AWS native storage options that support data-at-rest encryption.

➔     Scan images for vulnerabilities regularly—vulnerable binaries and application libraries can be found in container images. The best way to avoid threats is to scan images with an automated scanner regularly.

➔     Network policies— identify the source and destination pods using pod selectors and labels.

Microsoft Azure and Google Cloud are the top two cloud service providers, ranking second and third to Amazon Web Services, respectively (AWS). Despite its engineering prowess, Google Cloud, launched in 2008, trails AWS and Azure in market share.

Credit Suisse analyst Phil Winslow believes Azure will close the revenue gap with AWS while widening the gap with Google Cloud. He argues that Azure will benefit from significant changes in how businesses structure their IT infrastructure rather than simply shifting specific applications to the cloud.

According to a survey conducted earlier this year, Azure has surpassed AWS in popularity. Around 80% of respondents said they used Azure, while 77% said they used AWS.

Alphabet CEO Sundar Pichai, on the other hand, recently stated that cloud computing is one of Google’s fastest-growing businesses. Last month, Thomas Kurian, CEO of Google Cloud, noted that the company’s goal is to simplify all the technology that businesses require. Regarding market share, Google will have around 10% of the global market in the second quarter of 2022. According to Statista, Azure comes second with a market share of 21%.

Enterprise customers

One of the factors that favored Microsoft was its background in the enterprise business. This is something Google does not have. Microsoft sells a wide range of products, including Office, Windows, Dynamics, and Outlook, and it was easier for them to upsell cloud services to enterprise customers.

From the standpoint of these companies, it made more sense to go with Microsoft because they had previously used its products, which their employees were familiar with. Most of the Fortune 500 is on Azure as they want seamless security and APIs regardless of the environment.

Google’s strategy of convincing businesses to do things their way rather than paying attention to what the customer needs did not help their cause.

Furthermore, Microsoft has used vendor lock-in strategies, which are not new to the company. Microsoft has successfully leveraged its partner ecosystem to cross-sell its cloud solutions over the years, allowing Azure to become the world’s second-largest cloud service provider.

Data centers

In terms of infrastructure, Google Cloud lags behind Microsoft. Microsoft’s cloud infrastructure is massive, and Google must invest significantly more time and money to match Azure’s capabilities.

Microsoft Azure does not disclose the locations of its data centers; however, according to estimates, Microsoft operates over 200 physical data centers across 35 countries in 59 regions and 113 availability zones. In addition, 19 areas and 51 availability zones are being developed. Google Cloud, on the other hand, operates approximately 30 data centers in 35 regions and 106 availability zones spread across more than 200 countries and territories.

However, Google is adding nine more regions, bringing the total number of Google Cloud data centers to 44 by 2024. During Google Cloud Next 22, the company announced new Google Cloud regions for Austria, Greece, Norway, South Africa, and Sweden.

Although Google Cloud cannot compete with Azure in terms of infrastructure, it provides competitive pricing across all cloud services.

Services available

Google Cloud and Microsoft Azure provide their customers with a wide range of services, from storage and computing to networking. AWS and Azure provide over 100 different services; however, Google Cloud only provides about 60.

In terms of services, Azure again takes the lead, providing a well-rounded set of storage services; Google, on the other hand, has fewer options.

Google Cloud has the most competitive pricing for computing services. However, Azure provides a discount model that is appealing to existing Microsoft customers. Furthermore, Google Cloud’s salesforce is small compared to AWS and Google. In 2019, Google Cloud CEO Thomas Kurian acknowledged that their sales force is one-tenth to one-fifteenth the size of AWS and Microsoft Azure.

Kurian has extensively hired personnel over the years to bolster its workforce to remain competitive. The most notable addition in 2019 was SAP veteran Robert Enslin.

One advantage Google has is that Microsoft has a much more demanding learning curve. To overtake Azure, Google would need to do much more than offer lower prices and a smoother learning curve across all deployments.

What comes next?

The company announced a series of infrastructure and migration updates at this year’s Google Cloud Next 22 conference to help better organizations run on Google Cloud, at the edge, or in their data centers. Google announced Dual Run to assist businesses in migrating their decades-old mainframes to the cloud. It also revealed new developments in Google Workspace and its partner ecosystem.

“Google Cloud is what enables us to share innovation and investment across Google with companies, governments, and organizations around the world,” Pichai said during the Next ’22 opening session.

The tech titan also announced that beginning in 2023, customers will be able to pay for cloud services with cryptocurrencies. Google has partnered with Coinbase, a US-based cryptocurrency exchange, to facilitate crypto payments.

Bottom Line:

Google has built some of the best developer products in terms of automating microservices and container orchestration with Kubernetes and ASIC chips (TPUs) that compete with Nvidia. Cloud computing is capital-intensive, so if Google can’t find its footing, ad-driven margins may suffer in the short term.

It is impossible to predict who will lead software and AI applications (or when) because the main competitors will be hundreds (if not thousands) of startups. With that said, we at Linux 2Cloud believe healthcare is an example of a vertical where Google’s data experience can provide a significant competitive advantage. Alphabet may have a competitive advantage in AI/ML software, whereas this analysis focuses on infrastructure. A catalyst may emerge for Google Cloud to gain a larger share, but the strategy is not clear now.

Cloud computing is one of the most popular and in-demand employment fields today. The breadth of cloud computing has lately expanded as more businesses recognize the value of incorporating these technologies into their operations. 

A cloud computing professional’s annual salary in India might reach INR 10,000,000; thus, you can see how profitable this career is! 

However, before learning cloud computing, you must first become acquainted with several topics. This article will walk you through all cloud computing essentials to get you started. 

Cloud computing prerequisites 

Cloud computing is a complex field requiring knowledge of various areas due to its ties to numerous technologies. In this post, we’ll provide you with the required facts to answer this question and ensure that you’re ready to begin learning cloud computing without fear. To begin learning cloud computing, familiarise yourself with the following topics: 

Programming Capabilities 

Because you’ll be dealing with numerous programming languages as a cloud computing specialist, you’ll require good programming skills. Programming languages used by cloud computing specialists include Java, PHP, Python, and.NET. Because each of these languages has specific advantages, you should concentrate on gaining an essential mastery of each. 

Python, for example, includes several libraries that help with various programming tasks. On the other hand, PHP is required for the development of cloud computing applications. 

Knowing how to code and write programmes will also assist you in becoming a cloud computing specialist. Python is an excellent place to start because it has a straightforward syntax and doesn’t require any prior coding knowledge if you’re new to programming. 

Database understanding

Databases enable businesses to store and retrieve large amounts of data quickly. Professionals in cloud computing assist their organizations by establishing and administering cloud-based databases. As a result, understanding database functionality is critical. 

Furthermore, cloud-based databases have grown in popularity in recent years since they allow an organization to reap the benefits of having a database without investing in the necessary infrastructure. 

It would be best if you learned related technologies and the fundamentals of databases. The SQL programming language is used to administer a relational database management system. Other popular database technologies include MongoDB, MySQL, Apache Hadoop, and SQL. 

Knowledge of Operating Systems 

It would be best if you were conversant with the fundamentals of operating systems like Windows, macOS, and Linux. Because Linux is a frequently used solution among businesses for cloud computing deployments, it is a little more essential than the other operating systems. 

This is the most basic requirement for cloud computing because learning how an operating system works takes very little time. Most of the principles will be recognizable to anyone who has used a computer or similar device. 

Understanding of Virtualization 

Establishing virtual devices, infrastructures, and servers on a single computing system is virtualization. In this method, you construct a software-based virtual representation of another device, such as virtual storage, a network, or an application. Virtualization assists businesses in lowering operating costs by allowing them to increase the number of available software devices without expanding hardware. 

Before learning virtualization, you must first understand the fundamentals of an operating system. You should be able to construct a virtual machine and several virtual machines on your PC. 

Networking Fundamentals 

After you’ve mastered virtualization, you should concentrate on networking. Networking in cloud computing is concerned with hosting part or all network resources in the cloud. Virtual firewalls, virtual routers, network management software, bandwidth, and so on are all included. 

It would help if you began by studying IP addresses and how they work as a novice. Understanding the concept of IP addresses is essential for studying advanced networking topics. The network allows the user to connect to the cloud services in a cloud-based system. 

The network not only connects consumers to the cloud service but also connects the various components of the cloud-based solution (servers and storage nodes). 

Cloud types and the difference between public, private, and hybrid clouds

Mainly there are three different ways to use cloud computing. There are three types of clouds: public, private, and hybrid. The terms “public cloud” and “private cloud” are regularly used in today’s market. Let’s look at what they mean and how they differ from public and private clouds. 

● Public Cloud: 

This is a publicly accessible platform for storing data and running virtual machines. This can be accomplished either through programming or on its own. Individuals do not need to spend time and effort purchasing actual servers and can get started right away. Pay per approach public clouds are accessible to utilize. 

● Private Cloud: 

A private cloud is an ideal solution if a business needs a cloud entirely for them. In addition to the flexibility, a data center on the premises can be used for security and regulatory purposes. A dedicated specialist must manage the private cloud framework. 

● Hybrid Cloud: 

A hybrid cloud combines public and private clouds. Those who employ a hybrid cloud for particular business needs can benefit from the combination. 

Providers of Cloud Servers 

Today’s well-known Cloud Server providers include: 

● Amazon Web Services: 

A well-known provider for seamless integrations and services available. 

● Microsoft Azure: 

An excellent option for businesses already familiar with Microsoft products. 

● Google Cloud Platform: 

Designed for developers who need to develop and deploy cloud applications quickly. 

Conclusion 

It’s no surprise that such a broad and complex area as cloud computing has so many requirements. While the learning process may appear complicated, with effort and the correct professional supervision, you can master it.

Services Provided By Aws

AWS provides its services to businesses through dozens of data centers in Availability Zones (AZs) located in various regions around the world. Each area has a number of AZs, each of which has a number of physical data centers. The regions and AZs are all linked together by low-latency network links, resulting in a pool of highly reliable infrastructure resources that can withstand the failure of entire data centers or individual servers.

You can easily create an AWS account and reap the benefits of AWS services. One of the best features is that you only have to pay for the services you use; there is no need to pay extra.

Top Reasons To Learn AWS

AWS is more secure, cost-effective, and efficient than its competitors such as Alibaba, Google, and IBM, and as a result, major corporations use their services. Learning or selecting AWS is not only beneficial for students, but it is also a good option for industries looking to improve their business. We have already mentioned that many industries are migrating to AWS, so there is no doubt that career opportunities are plentiful in this field. According to Google trends, organizations are experiencing severe skill shortages in AWS. Professionals looking for a lucrative career should look into AWS.

More than 350, 000 professionals are needed to fill the cloud job titles. AWS skills are at the top of the list of the most in-demand skills for employers today, and if you are concerned about the salary in this field, visit Glassdoor. Now, let’s go over some more reasons why you should learn AWS.

• Individualization

The AWS platform provides its users with a high level of customization to meet the needs of individual businesses. Customer-defined tagging, for example, enables users to easily monitor and manage specific resources. AWS tags can also be used for cost tracking, security, and automation.

• Security

When it comes to choosing any service, security has always been a major concern for enterprises, and cloud security has always been a source of contention. AWS is well aware of this concern. AWS offers its customers the highest level of data privacy and security, regardless of their business size. Whether you are a small startup or a large corporation, AWS has extensive security support that provides real-time insight into suspicious activity and potential vulnerabilities. AWS protects data privacy by implementing physical security, fine-grained access, and data locality control. There are no additional fees for IAM (Identity and Access Management). IAM enables users to manage who is authenticated and authorized to access resources.

• Access is provided for free, and prices are reasonable.

A free-tier AWS account can be created by novices, trainees, and apprentices, as well as anyone who wants to gain hands-on experience with AWS. The free-tier account level grants access to certain free services that never expire. There are other accounts that are free for a year, as well as some premium services that are available for a free trial. Among the services included are EC2, S3, elastic load balancing, and Amazon RDS. Although some of these services have usage limits, they are more than enough to learn about and become acquainted with what the flexible pay-as-you-go service will have to offer.

• Scalability and adaptability

Amazon has always placed a premium on scalability, right from the start. AWS services are always adaptable to your needs, and you can auto-scale them as needed. Businesses no longer have to deal with the constraints of physical computing infrastructure, and they can have on-demand access to servers and storage. Scalability allows for the automatic increase or decrease of resource capacity based on demand. Businesses can scale up or down based on their needs thanks to flexibility. You can start or stop any service at any instance of time.

• Application Programming Interface (API) (API)

AWS APIs are available in a variety of programming languages, allowing you to programmatically manage your infrastructure. Third-party services such as CloudRanger, Quintly, and Tango card assist you in launching a new instance, taking backups, and utilizing all of AWS’s time and cost-saving features. CloudRangers, for example, uses a visual representation of the cloud to assist the company in understanding it. Quintly offers social media analytics for brands in a centralized dashboard.

• Scheduling

Scheduling means that you can start and stop AWS services at predetermined times, which means that you can schedule your services to run at a specific time, on a specific day, or even when a specific event occurs. AWS, for example, lets you schedule services like Elastic Compute Cloud (EC2) and Relational Database Service (RDS). You are not required to provide these services on weekends or during off-hours. Scripting is also not required with the help of third-party tools such as CloudRanger.

• PaaS Providers

We’ve talked about how AWS is highly scalable. It replicates similar methods in completed services for data-warehousing, backup, database, transcoding, caching, application management, storage, and infrastructure management. This is extremely beneficial in terms of reducing the total time and energy spent on infrastructure setup and management. This helps to reduce the market’s overall cost.

• Recovery

Data backup is essential in every business to avoid a disaster or a large loss. A small amount of downtime, service interruption, or data loss results in disaster. In the case of AWS, there are a variety of cloud-based recovery options available to help you reclaim your data and IT infrastructure. If one of the servers loses the data, it can be recovered.

• Consistency and dependability

We’ve already established that AWS is a useful platform for storing backups of your data. AWS’s best selling point is also its reliability, which is achieved through multiple backups of servers in multiple physical locations. According to a 2015 report, AWS had the lowest downtime. AWS has been “far better than either Microsoft or Google at keeping its public cloud service running.” To write a reliable and stable application in AWS, you must first understand the AWS consistency models.

• Global Architecture

When it comes to selecting a service, we must first determine whether the service is available in the desired location. When it is all about cloud service providers, AWS is a global leader. It is famous for its availability zones. Around the world, the AWS cloud spans 44 availability zones, 18 geographical regions, and one local region. Each AWS region has a number of availability zones and data centers. Many more availability zones are currently being developed and will be visible in the near future.

Bottom Line

Is AWS training the right path for you? That is determined by the type of career you wish to pursue. If you decide to go with the cloud, the best way to get started and boost your employability is to obtain AWS skills and certifications. There are numerous resources available for both beginners and professionals interested in learning AWS.

T2 Instances are intended to provide moderate baseline performance as well as the ability to burst to higher performance as needed by the workload. 

10. What is AWS Key-Pairs? 

Key-Pairs are password-protected login credentials for your Virtual Machines. To connect to the instances, Key-Pairs with a Public Key and a Private Key can be used. 

11. How many Subnets are allowed in a VPC? 

Each VPC can have up to 200 Subnets. 

12. Describe the various types of cloud services. 

Cloud Services are classified into the following categories: 

A. Software as a Service (SaaS) (SaaS) 

B. Data as a Service (DAAS) (DaaS) 

C. Platform as a Service (PAAS) (PaaS) 

D. Infrastructure as a Service (IaaS) (IaaS) 

13. How do you upgrade or downgrade a system with little to no downtime? 

The following migration steps can be used to upgrade or downgrade a system with near-zero downtime: 

➔ Launch the EC2 console. 

➔ Select the AMI Operating System. 

➔ Initiate a new instance with the new instance type. 

➔ Install all the updates 

➔ Setup applications 

➔ Check to see if the instance is operational. 

➔ If everything is fine, deploy the new instance and replace the old one. ➔ Once installed, you can upgrade or downgrade the system with little to no downtime. 

14. Is there an alternative tool to the console for logging into the cloud environment? 

The following can assist you in logging into AWS resources: 

➔ Putty 

➔ AWS CLI for Linux 

➔ AWS CLI for Windows 

➔ AWS CLI for Windows CMD 

➔ AWS SDK 

➔ Eclipse 

15. What are the different types of virtualization in AWS, and how do they differ? 

In AWS, the three major types of virtualization are: 

➔ Hardware Virtual Machine (HVM) 

It is a fully virtualized hardware in which all virtual machines operate independently of one another. These virtual machines boot by executing a master boot record in your image’s root block device. 

➔ Paravirtualization (PV) 

The bootloader that boots the PV AMIs is called paravirtualization-GRUB. The PV-GRUB chain executes the kernel that was specified in the menu. 

➔ Paravirtualization on HVM 

PV on HVM enables operating systems to take advantage of the host’s storage and network I/O. 

16. Name a few AWS services that are not region-specific. 

AWS services that are not region-specific include: 

➔ IAM 

➔ Route 53 

➔ Web Application Firewall 

➔ CloudFront 

17. What exactly is CloudWatch? 

Amazon CloudWatch contributes to the triggering of alarms based on a variety of metrics. Monitors AWS environments such as CPU utilization, EC2, Amazon RDS instances, Amazon SQS, S3, Load Balancer, SNS, and so on. 

18. What is the distinction between stopping and terminating an EC2 instance? 

While you may believe that stopping and terminating are synonymous, there is a distinction. When you stop an EC2 instance, it performs a normal shutdown and moves to a stopped state. When you terminate the instance, it is transferred to a stopped state, and the EBS volumes attached to it are deleted and cannot be recovered. 

19. Explain briefly about AWS? 

Amazon Web Services (AWS) is the world’s most comprehensive and widely used cloud platform, with over 200 fully-featured services available from data centers around the world. 

AWS provides services such as servers, storage, networking, remote computing, email, mobile development, and security. 

20. Why should you use AWS for DevOps? 

There are numerous advantages to utilizing AWS for DevOps. Here are a few examples: 

➔ AWS is a ready-to-use service that does not necessitate any additional software or setups to get started. 

➔ Whether it’s one instance or hundreds at a time, AWS’s provision of computational resources is limitless. 

➔ The AWS pay-as-you-go policy will keep your pricing and budgets in check, ensuring that you can mobilize enough while receiving an equal return on investment. 

➔ AWS brings DevOps practices closer to automation, allowing you to build faster and achieve better results in terms of development, deployment, and testing processes. 

➔ AWS services are easily accessible via the command-line interface or through the use of SDKs and APIs, making them highly programmable and effective. 

21. What do you know about AWS in DevOps? 

AWS is Amazon’s cloud service platform that enables users to easily carry out DevOps practices. The tools provided will greatly assist in automating manual tasks, allowing teams to manage complex environments and engineers to work efficiently with the high velocity that DevOps provides. 

22. What is AWS DevOps CodePipeline? 

AWS CodePipeline is a service that provides continuous integration and delivery services. It also includes provisions for infrastructure updates. With the set release model protocols that a user defines, operations such as building, testing, and deploying after every single build become very simple. CodePipeline ensures that you can reliably and quickly deliver new software updates and features. 

23. How can a company such as Amazon.com benefit from AWS DevOps? 

Amazon, like any other eCommerce site, is primarily concerned with automating all frontend and backend activities seamlessly. This is easily accomplished when combined with CodeDeploy, allowing developers to focus on building the product rather than deployment methodologies. 

24. What exactly is AWS Lambda in the context of AWS DevOps? 

AWS Lambda is a computation service that allows users to run code without explicitly provisioning or managing servers. Users can run any piece of code for their applications or services using AWS Lambda without prior integration. It’s as simple as uploading a piece of code and letting Lambda handle everything else necessary to run and scale it. 

25. What is AWS DevOps Microservices? 

Microservice architectures are the design approaches used when constructing a single application as a collection of services. Each of these services has its process structure and communicates with the others via a structured interface that is both lightweight and simple to use. The majority of this communication is based on HTTP and API requests.
