Introduction to AWS ( Amazon Webservices)

·       

•      Cloud formation – You have access to a consistent template-based environment for development, test, and production purposes. With an increasing level of operational control.

·       Because of elasticity –

•       Quickly deploy applications.
•       Instantly scale up as the workload grows.
•       Instantly shutdown resources when no longer required.

• Aws tools - Autoscaling, Elastic load balancing.

• Your application can automatically scale up or down based on your demand.

 

• ·       Amazon massive infrastructure you have to compute in storage resources whenever you need them.

• ·       With AWS you can easily deploy your system in multiple regions around the world while providing a lower latency

• ·       Reliability is the ability of a system infrastructure or service failures.

• ·       In the cloud, computing reliability means being able to acquire computing resources to meet demand and mitigate disruptions.

·       To achieve reliability

•       your architecture and systems must have a well-planned foundation that handles changes in demand.
•       Detect failures.
•       Automatically heals itself.

·       Reliability is the key component of the AWS cloud.

·       AWS region – a separate geographic area that has multiple isolated locations are known as 

availability zones which consist of one or more discrete data centers.

·       Fault tolerance – A system can remain operational even some of the components of the system fail.

·       AWS cloud-based products – compute storage, databases, analytics, networking, mobile, developer tools, IoT, security and enterprise applications.
