    Study Notes

    AWS Services: EC2, S3, RDS, VPC, Lambda

    Amazon Web Services (AWS) offers a comprehensive suite of cloud services to support a broad range of IT infrastructures. In this article, we'll delve into five of AWS's most popular services: Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), Amazon Relational Database Service (RDS), Amazon Virtual Private Cloud (VPC), and Amazon Lambda.

    Elastic Compute Cloud (EC2)

    EC2 is a web service that provides secure, resizable compute capacity in the cloud. You can pay by the hour or second for as many or as few Amazon Elastic Compute Cloud (EC2) instances as you need. EC2 instances can be launched to run applications like web servers, databases, or other applications that require high-performance computing resources.

    Amazon Simple Storage Service (S3)

    S3 is an object storage service designed to meet the needs of a wide range of use cases, such as data backup, disaster recovery, and archiving. S3 provides high durability and high-speed data access. S3's storage classes, like Standard, IA (Infrequent Access), and Glacier, offer varied cost and performance options to optimize storage for specific use cases.

    Amazon Relational Database Service (RDS)

    RDS is a managed service that makes it easy to set up, operate, and scale relational databases in the cloud. RDS supports several database engines, including MySQL, PostgreSQL, and Oracle. RDS manages time-consuming database administration tasks, freeing developers to focus on their applications.

    Amazon Virtual Private Cloud (VPC)

    VPC lets you provision a logically isolated section of the AWS cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways.

    Amazon Lambda

    Lambda allows you to run code without provisioning or managing servers. Lambda automatically scales your code to match traffic, which reduces your operational costs. Lambda integrates with other AWS services, such as Amazon S3 and Amazon DynamoDB, to enable various use cases like app backends, data processing, and real-time stream processing.

    Connecting Lambda to Other AWS Services

    To connect a Lambda function to an AWS service, such as S3 or RDS, you must configure the necessary networking settings. When connecting a Lambda function to an RDS instance in the same VPC, you set up inbound and outbound rules at the security group level. If the Lambda function and RDS instance are in different VPCs, you use VPC peering or AWS PrivateLink to connect the resources.

    A Lambda function connected to an RDS instance cannot directly access the internet. If the Lambda function requires access to the internet, you must route internet-bound traffic to a NAT gateway in a public subnet.

    Best Practices

    When deploying an RDS instance into isolated subnets within a VPC, it's recommended to use VPC peering or AWS PrivateLink to connect the RDS instance to a Lambda function in a different VPC. Keeping the RDS instance in a VPC is a best practice for security reasons, as public databases should use NoSQL services like DynamoDB.

    Conclusion

    AWS's diverse suite of services, including EC2, S3, RDS, VPC, and Lambda, provides developers with powerful tools to build and scale applications in the cloud. Each service offers unique advantages, such as high-performance computing, cost-effective storage, and serverless computing. By understanding how to connect AWS services, developers can create efficient and secure architectures that meet their needs.
