AMAZON WEB SERVICES

Why AWS?

Data durability due to replication of information across multiple redundant storage arrays.

Highly secure data due to regular audits of infrastructural security by AWS.

Large number of geographical locations with multiple points of presence within each allow highly available environments to be built.

Economies of scale mean pay-as-you-go infrastructure is very cost effective.

Scale up or scale out your computing resources effortlessly.

Environments can “self-heal” by making use of Auto Scaling Groups and Elastic Load Balancers to automatically replace problem instances.

Simple to create private networks which ensure no data can be intercepted in transit within AWS’ network.

Features

Globally distributed DNS

AWS Route53 provides highly available DNS hosting for internal and external purposes.

Elastic Load Balancer

Highly available managed load balancers provide stability and redundancy to any web application, allowing any number of instances to serve content seamlessly to the client.

Isolated database and file system

Utilising the Relational Database Service and Elastic File System we can ensure that databases and application files are hosted completely independently of each other within fully redundant, highly available managed services.

Policy based autoscaling

The underlying instances serving different parts of an application are automatically increased or decreased in response to events like a burst of traffic or high latency.

Network isolation

Each environment, from development, testing to production, is self-contained within its own network. Each network has its own set of subnets, access control lists and security groups to ensure security of the infrastructure within.

Automated daily snapshots

All production data is backed up daily using EBS snapshots. Snapshots are incremental block level backups stored in the highly redundant S3 storage and allow point in time restoration of whole volumes at the click of a button.
