Introduction to Amazon Web Services
Published 2 years ago
In this article, we will take a general look at Amazon Web Services (AWS). As usual, we will not go deep into technical details, first of all, because it is so big that it's hard to imagine all its possibilities and second we don't have expertise in all its services. We will rather try to find business advantages from using AWS.
Amazon is the biggest e-commerce platform in the world at the moment and in order to have all their operations run properly they've built a very powerful IT infrastructure. Seeing the success of their creation, they decided to share it with the world and everybody can take advantage of all their services available in the cloud. At the moment AWS is a big chunk of the overall Amazon business and it has the lion share of the cloud services category, followed by Google Cloud and Microsoft Azure.
IaaS stands for Infrastructure As A Service and uses decentralized or distributed IT infrastructure to make several IT resources available on demand. AWS provide services like storage (file and database), computing, networking, management tools, artificial intelligence and much more which allow you to combine them as you need and obtain your own IT infrastructure.
AWS successfully adopted the concept of Pay As You Go, meaning that you only pay for the resources that you use. For startups, AWS is a good choice because it provides a free tier for almost all their services. This allows startups to validate their idea for free. This is very important for startups in their initial stage. If the idea is validated, scaling is the next step and AWS makes it very easy to achieve. Also, as a startup, you don't have to take care of expenses like hardware, software, power, bandwidth, security and availability - you get it out of the box. So what is the advantage of using AWS? Let's go through some of them.
You have more time to concentrate on core business activities by leveraging the instant availability of new features and services. Also, you can run different services on AWS separately to cut costs or together in order to have your own infrastructure. You can even combine different services from different service providers or to use some of your own existent applications.
Like we already mentioned AWS provide a free tier for their services you can play with. After you reach the free tier limit you start to pay after you used it but only for resources that you used and only for the amount that you used. So no upfront payments and no long-term commitment and no minimum expense. So you have flexibility also here.
Scalability and elasticity
AWS can grow along with your application by providing easy ways to scale with a click of a button. You can even use auto-scaling techniques to allow your application to manage the resources it needs. Elastic load balancing automatically distributes incoming application traffic achieving maximum availability.
Since inception Amazon had to continuously work on the security of their systems and AWS take advantage of all this work. By using AWS we can also rely on the strong security layer they are providing. AWS is also providing access management tools for their users and a part of the responsibility is also on the shoulders of these users because improper use of these tools can have bad consequences on the critical data. In general, security is a topic for a separate article.
Conclusion: More and more businesses are migrating to the cloud. The services provided by the cloud companies are evolving continuously. Everybody can take advantage of cheap resources and ready to use solutions. The only thing that you need is an expert to help you with setup, migration and managing the infrastructure.
