How to Accessing the Platform
Start with the AWS Management Console, the AWS Command Line Interface (CLI), or the AWS Software Development Kits (SDKs).
The AWS Management Console is a web application for managing AWS Cloud services. The console provides an intuitive user interface for performing many tasks. Each service has its own console, which can be accessed from the AWS Management Console. The console also provides information about the account and billing.
The AWS Command Line Interface (CLI) is a unified tool used to manage AWS Cloud services. With just one tool to download and configure, you can control multiple services from the command line and automate them through scripts.
The AWS Software Development Kits (SDKs) provide an application programming interface (API) that interacts with the web services that fundamentally make up the AWS platform. The SDKs provide support for many different programming languages and platforms to allow you to work with your preferred language. While you can certainly make HTTP calls directly to the web service endpoints, using the SDKs can take the complexity out of coding by providing programmatic access for many of the services.
Compute and Networking Services
AWS provides a variety of compute and networking services to deliver core functionality for businesses to develop and run their workloads. These compute and networking services can be leveraged with the storage, database, and application services to provide a complete solution for computing, query processing, and storage across a wide range of applications. This section offers a high-level description of the core computing and networking services.
Amazon Elastic Compute Cloud (Amazon EC2)
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It allows organizations to obtain and configure virtual servers in Amazon’s data centers and to harness those resources to build and host software systems. Organizations can select from a variety of operating systems and resource configurations (memory, CPU, storage, and so on) that are optimal for the application profile of each workload. Amazon EC2 presents a true virtual computing environment, allowing organizations to launch compute resources with a variety of operating systems, load them with custom applications, and manage network access permissions while maintaining complete control.
AWS Lambda is a zero-administration compute platform for back-end web developers that runs your code for you on the AWS Cloud and provides you with a fine-grained pricing structure. AWS Lambda runs your back-end code on its own AWS compute fleet of Amazon EC2 instances across multiple Availability Zones in a region, which provides the high availability, security, performance, and scalability of the AWS infrastructure.
Auto Scaling allows organizations to scale Amazon EC2 capacity up or down automatically according to conditions defined for the particular workload . Not only can it be used to help maintain application availability and ensure that the desired number of Amazon EC2 instances are running, but it also allows resources to scale in and out to match the demands of dynamic workloads. Instead of provisioning for peak load, organizations can optimize costs and use only the capacity that is actually needed.
Auto Scaling is well suited both to applications that have stable demand patterns and to applications that experience hourly, daily, or weekly variability in usage.
Elastic Load Balancing
Elastic Load Balancing automatically distributes incoming application traffic across multiple Amazon EC2 instances in the cloud. It enables organizations to achieve greater levels of fault tolerance in their applications, seamlessly providing the required amount of load balancing capacity needed to distribute application traffic.
