AWS is one of the leading cloud computing platforms, which offers a wide array of services that includes compute, storage, networking, databases, machine learning, analytics, and more. It is designed to help businesses scale their infrastructure, reduce costs, and improve flexibility.
AWS Server Services
AWS provides a number of types of server instances depending on different business requirements. The main server-related services include the following:
Amazon EC2: This is the most utilized AWS service, which provides virtual machines in the cloud that one can use to run applications. To run VMs in the cloud, users can choose from a wide variety of instance types based on their specific needs. The instances of EC2 are scalable, which means one can start small and increase the resources whenever needed.
Amazon Lightsail: Lightsail was an AWS watered-down version of EC2, designed to make it easier to use compared to EC2 for customers looking for easier ways to deploy and manage virtual servers. Thus, it comes with pre-configured stacks that feature computation, networking, and storage-all ideal for smaller workloads, blogs, and web apps.
AWS Lambda: Lambda is a serverless compute service that runs code without requiring the developer/administrator to provision or manage servers. It’s event-driven-code gets executed as a response to events such as file uploading and database changes-which enables developers to focus on writing purely about code.
Amazon ECS: This is a fully managed container orchestration service. It shall enable customers to run containerized applications that utilize Docker containers in production and to scale. That would be the main role it plays in simplifying how developers manage clusters of EC2 instances running containers.
AWS EKS: EKS is an AWS-managed Kubernetes Service. With EKS, you will run and scale your Kubernetes apps on AWS without managing the underlying infrastructure.
Pricing
Pricing for AWS servers is based on instance type, region, and duration of use. Here’s a general overview of how AWS pricing typically works:
Pricing by EC2:
On-Demand Instances: Pay for the Compute Capacity by the Hour or Second, Depending on the Instance Type, with No Long-Term Commitments.
Reserved Instances: You can reserve instances for one or three years and get a significant discount in exchange for committing to a certain level of usage.
Spot Instances: These are the spare instance availability in EC2, which is given at a discounted price and may be terminated when demand reaches the threshold value set by AWS in its algorithms.
For example, the per hour cost of an on-demand t3.micro in the US East (N. Virginia) region is approximately $0.0104 per hour, while larger instances such as m5.2xlarge can cost as much as $0.384 per hour.
Lightsail Pricing:
Lightsail has fixed pricing, starting as low as $3.50 a month for a basic instance of 512MB of memory and 1vCPU. Pricing increases as resources like memory and storage scale up.
Lambda Pricing:
AWS Lambda is charged based on the number of requests and time consumed for the execution of your code. The first 1 million requests per month are free; afterward, it will cost $0.20 per 1 million requests.
Cost Management Tools
AWS also offers budget management through the estimation of costs with the AWS Pricing Calculator and analyzing and optimizing usage patterns with AWS Cost Explorer.
Conclusion
By applying these tools, a company will be able to better budget and forecast its cloud-related expenses. Overall, AWS servers offer scalable solutions with flexible pricing models targeted at different business needs, from the tiniest startups to large enterprises.
