Introduction to AWS Services for Freshers
AWS (Amazon Web Services) is a comprehensive cloud computing platform that offers a wide range of services for computing, storage, networking, databases, analytics, machine learning, and more. With the increasing demand for cloud computing, AWS has become a highly sought-after skill in the industry. For freshers, getting certified in AWS can be a great way to kick-start their career. However, with so many services to learn, it can be overwhelming to know where to start. In this article, we will explore the essential AWS services that freshers should know for certification.
Computing Services
AWS provides a range of computing services that enable users to run and manage applications in the cloud. The most essential computing services for freshers to know are EC2 (Elastic Compute Cloud), Lambda, and Elastic Beanstalk. EC2 provides virtual servers, known as instances, which can be used to run applications. Lambda is a serverless compute service that allows users to run code without provisioning or managing servers. Elastic Beanstalk is a service that enables users to deploy web applications and services without worrying about the underlying infrastructure. For example, a company can use EC2 to host its website, Lambda to process image uploads, and Elastic Beanstalk to deploy a web application.
Storage Services
AWS provides a range of storage services that enable users to store and manage data in the cloud. The most essential storage services for freshers to know are S3 (Simple Storage Service), EBS (Elastic Block Store), and EFS (Elastic File System). S3 is an object storage service that allows users to store and retrieve large amounts of data. EBS provides block-level storage for EC2 instances, while EFS provides file-level storage for EC2 instances. For example, a company can use S3 to store images and videos, EBS to store data for a database, and EFS to store files for a web application.
Database Services
AWS provides a range of database services that enable users to manage and analyze data in the cloud. The most essential database services for freshers to know are RDS (Relational Database Service), DynamoDB, and Redshift. RDS provides a managed relational database service that supports popular database engines such as MySQL and PostgreSQL. DynamoDB is a NoSQL database service that provides fast and predictable performance. Redshift is a data warehousing service that enables users to analyze large amounts of data. For example, a company can use RDS to manage customer data, DynamoDB to store real-time analytics data, and Redshift to analyze sales data.
Security, Identity, and Compliance Services
AWS provides a range of security, identity, and compliance services that enable users to secure and manage their resources in the cloud. The most essential services for freshers to know are IAM (Identity and Access Management), Cognito, and Inspector. IAM provides a service that enables users to manage access to AWS resources. Cognito provides a user identity and access service that enables users to manage user authentication and authorization. Inspector provides a service that enables users to assess the security and compliance of their AWS resources. For example, a company can use IAM to manage access to EC2 instances, Cognito to manage user authentication for a web application, and Inspector to assess the security of its AWS resources.
Networking Services
AWS provides a range of networking services that enable users to manage and secure their network resources in the cloud. The most essential networking services for freshers to know are VPC (Virtual Private Cloud), Route 53, and Direct Connect. VPC provides a virtual networking service that enables users to create and manage their own virtual networks. Route 53 provides a domain name system (DNS) service that enables users to manage domain names and route traffic. Direct Connect provides a service that enables users to establish a dedicated network connection from their premises to AWS. For example, a company can use VPC to create a virtual network for its EC2 instances, Route 53 to manage its domain names, and Direct Connect to establish a dedicated network connection to AWS.
Conclusion
In conclusion, AWS provides a wide range of services that enable users to build, deploy, and manage applications in the cloud. For freshers, getting certified in AWS can be a great way to kick-start their career. The essential AWS services for freshers to know include computing services such as EC2, Lambda, and Elastic Beanstalk, storage services such as S3, EBS, and EFS, database services such as RDS, DynamoDB, and Redshift, security, identity, and compliance services such as IAM, Cognito, and Inspector, and networking services such as VPC, Route 53, and Direct Connect. By mastering these services, freshers can gain a solid foundation in AWS and improve their chances of passing the AWS certification exam.
