You can also use backup, recovery, and failover features to prevent data loss and downtime.Security: Cloud computing offers built-in security measures, such as encryption, firewalls, identity and access management, and compliance standards. You can also use additional tools and services to enhance your security posture and protect your data and applications.Innovation: It enables you to experiment and innovate faster by providing access to the latest technologies and services. For instance, artificial intelligence, machine learning, big data, IoT, and serverless computing. You can also integrate and orchestrate different services to create new solutions and value propositions.As a DevOps engineer, you can leverage these benefits to deliver better products and services faster and more efficiently. Learn about Cloud ComputingTo learn cloud computing, you need to understand the basic concepts and principles that underpin it. You also need to familiarize yourself with the different types of cloud computing and the major cloud platforms that offer them. Types of Cloud ComputingThere are three main types of cloud computing, based on the level of abstraction and control they provide: Infrastructure as a Service (IaaS): This is the most basic type of cloud computing, where you rent servers, storage, and networking resources from a cloud provider. It gives you full control over the resources’ configuration and management. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).Platform as a Service (PaaS): This is a type of cloud computing where you use a cloud provider's platform to develop, deploy, and run your applications without worrying about the underlying infrastructure. The cloud provider manages the servers, storage, and networking resources, as well as the operating system, middleware, and runtime environment. You only focus on the code and the logic of your applications. Examples of PaaS providers are AWS Elastic Beanstalk, Azure App Service, and Google App Engine.Software as a Service (SaaS): This is a type of cloud computing where you use a cloud provider's software applications over the internet without installing or maintaining them on your own devices. The cloud provider manages the infrastructure, platform, and application, and you only access them through a web browser or a mobile app. Examples of SaaS providers are Gmail, Salesforce, and Zoom.Check our article on “What is Cloud Computing” to learn more about cloud computing services, cloud computing deployment model, its advantages and limitations. Cloud PlatformsThere are many cloud platforms that offer different types of cloud computing services, but the top three that dominate the market are AWS, Azure, and GCP. These platforms have their own strengths and weaknesses, and you need to compare and contrast them to decide which one suits your needs and preferences. Below are some of the factors that you need to consider when choosing a cloud platform: Features and Services: Each cloud platform offers a variety of features and services, covering different domains and use cases, such as compute, storage, database, networking, security, analytics, AI, IoT, etc. You need to evaluate the quality, quantity, and diversity of the features and services that each platform offers and how they match your requirements and expectations.Pricing and Billing: The pricing and billing model are based on different parameters, such as resource type, usage, duration, region, etc. You need to understand the pricing and billing structure of each platform and how it affects your budget and spending. You also need to compare the cost-effectiveness and value proposition of each platform and how they align with your goals and outcomes.Documentation and Support: Go through their documentation to assess the support resources that each platform offers and how they help you learn and troubleshoot. You also need to consider the availability and responsiveness of the customer service and technical support that each platform provides.These are some of the factors you need to consider when choosing a cloud platform, but there may be others depending on your specific needs and preferences. You also need to recognize any gaps that you may have in your existing knowledge and skills before starting an in-depth learning journey. For example, you may need to brush up on your programming, scripting, or networking fundamentals or learn some new tools or frameworks that are relevant for cloud computing. Choose a Platform to Focus OnOnce you have a general understanding of cloud computing and its types, concepts, and platforms, you need to choose a platform to focus on for your learning. While it is possible to learn multiple cloud platforms, it is advisable to start with one platform initially and gain depth over breadth. This will help you master the core concepts and services of that platform and build confidence and competence in using them. The question then is, which platform should you choose? The answer depends on several factors, such as your personal interest, career goals, project requirements, employer preferences, etc. However, if you are looking for a general recommendation, we suggest picking AWS as your first cloud platform to learn. AWS is the oldest and largest cloud platform in the market, with a global presence and a dominant market share. According to a report by Synergy Research Group, AWS had a 31% share of the cloud infrastructure services market in Q4 2023, followed by Azure with 24% and GCP with 11%. AWS also had the highest annual revenue growth rate of 28% among the top three cloud platforms. AWS offers a comprehensive and diverse range of cloud services, covering almost every domain and use case imaginable, such as compute, storage, database, networking, security, analytics, AI, IoT, etc. It also has a rich and mature ecosystem of partners, customers, and developers who create and share valuable resources and solutions.
