What’s AWS ?

Amazon Web Services is a comprehensive, evolving cloud computing platform provided by Amazon that includes a mixture of infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and packaged-software-as-a-service (SaaS) offerings. AWS services can offer an organization tools such as compute power, database storage and content delivery services.

AWS (Amazon Web Services) is a Cloud Provider. It provide you with servers and services that you can use on demand and scale easily. It has revolutionized IT over time.

AWS Cloud History

It was internally established at in 2002. they understood that the IT departments could be outsourced. One of their key advantages was their Amazon infrastructure, so they thought, “You know what, maybe we can do IT for someone else, “for other people,” and they introduced their first publicly available product, SQS, in 2004. They revamped and expanded their service in 2006, adding SQS, S3, and EC2 to the mix. They then elaborated by saying, “You know what? We could be anywhere; we don’t have to be in America. Then fast forward to the present day, where there are a tonne of programmes still operating or previously operating on AWS, including NASA, Netflix, Air BNB, Dropbox, and Netflix.

Regions in AWS

AWS has Regions all around the world:

  • Names can be us-east-1, eu-west-3…
  • A region is a cluster of data centers.
  • Most AWS services are region-scoped

How to select an AWS Region ?

If you need to launch a new application,where should you do it?

  • Compliance with data governance and legal requirements: data never leaves a region without your explicit permission
  • Proximity to customers: reduced latency.
  • Available services within a Region: new services and new features aren’t available in every Region.
  • Pricing: pricing varies region to region and is transparent in the service pricing page.

let’s understand with example:

You are launching a new application. Where should you do it? Should you do it in America, in Europe in South America, or in Australia? Well, the answer is, of course, it depends.

Some factors that may impact your choice of an AWS region. The first one is compliance.

Sometimes governments want the data to be local to the country you are deploying the application. For example, France, data in France may have to stay in France and therefore you should launch your application in the French region. Then, there is also a concept of latency.

If most of your users are going to be in America, it makes a lot of sense to deploy your application in America, close to your users, because they will have a reduced latency. If you deploy your application in Australia and your users are in America, they will have a lot of lags in using your application. Also, not all regions have all services. Some regions do not have services. And so obviously if you are leveraging a service with your application, you need to make sure that the region you are deploying into is available and does have that service.

And finally, pricing does vary from region to region and you need to consult the applicant, the services, and pricing, (indistinct) to see what the differences are between the regions. But this could be obviously a factor that could impact your deployment of an application into a specific region. Now, availability zones are what actually is going into the region.

Availability Zones Of AWS

  • There will be many availability zones in each region. Usually three, with a minimum of two and a maximum of six. But three is more common. Example:
    • ap-southeast-2a
    • ap-southeast-2b
    • ap-southeast-2c
  • Each availability zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity.
  • They’re separate from each other, so that they’re isolated from disasters.
  • They’re connected with high bandwidth, ultra-low latency networking.

Point of Presence:

The only thing we need to know about AWS for the global infrastructure is the points of presence or edge locations.

  • Amazon has 216 Points of Presence (205 Edge Locations & 11 Regional Caches) in 84 cities across 42 countries.
  • When we offer material to end consumers with the least amount of latency as feasible, this will be incredibly beneficial.
