    Some of the main characteristics of AWS 

    If you want your applications to run the right way in the Amazon environment, it is important that you understand the key characteristics of the Amazon Web Services. After all, you can’t actually work with AWS if you don’t have much idea about how it works. When you plan to build your applications, you must keep the following AWS characteristics in mind: 

    • A wide range of services is offered by AWS. All these services are designed for delivering a single functionality set. All these services are stand alone, however; it is possible to mix them for meeting the particular requirements of your application. 
    • All the services are offered through APIs. Some people may prefer using the user interface of Amazon or any other third party. Others can also access AWS directly through the AWS software development kit or APIs. Regardless of how you choose to access these services, it is important to remember that the idiosyncrasies and functionalities of each service are unique.  
    • It is worth noting that the AWS infrastructure is, in fact, prone to failure. However, it is through redundancy that Amazon ends up being robust. Three copies are maintained for the data and computing associated with a service for which SLAs (Service Level Agreements) are offered by Amazon. 
    • The AWS model is an on-demand one, which requires you to only pay for what you use. Thanks to this pricing model, AWS can be really cost-effective. Particularly, when you first start developing an application, the costs are quite low. However, as the usage increases, the cost increases with it. So, tracking your usage is extremely necessary. 
    • AWS services are also offered on availability zone- and region-based partitioning. There are network traffic charges imposed if you access data in one region from EC2 instances in another region. So, if you want to maintain lower costs, it is important that you know where your applications have to run along with the location of your data.

    Helpful tips to design applications for AWS

    Amazon Web Services does indeed differ significantly from the traditional infrastructure. Hence, the outcomes won’t necessarily be the best if you attempt to apply the conventional application design principles. The following points must be kept in mind: 

    • Failure is a frequent occurrence: With Amazon Web Services, a lot of things fail all the time and you should be prepared for that. Particularly, EC2 instances can stop responding or fail altogether unexpectedly. Hence, you need to make sure your application is resilient to resource failure.  
    • Ensure application uptime by using redundancy: Following the operating principles of Amazon is advisable since there is a chance of AWS resources failing. Designing and implementing redundancy in applications is always recommended. With redundancy, your application is protected against resource failure.  
    • Applications should be designed for horizontal scaling: Whether you use AWS resources heavily or not, they will always incur costs. That is why it is important for your application to be able to scale up and down. It should shrink and grow its resources so you use only what you need for supporting the resilience and performance of your application.  
    • Maximize the use of open source components: An open-source software is always less expensive. Not only that, it is more compatible with sporadic use because of its licensing conditions. On the other hand, there is a major license fee associated with proprietary software, regardless of whether the software runs for 10 minutes or 10 years.  

    Uncommon ways of using AWS for your applications 

    The set of services offered by AWS is far more varied than most people would recognize. Most of them are familiar with the popular AWS products such as S3 and EC2 and use them frequently. However, not many end up exploring more with AWS for learning about other services that can be used for their applications. You can leverage additional AWS services for: 

    • Developing richer applications: There is an entire range of AWS services with unique capabilities of their own. For instance, you can provide a search within the application through ElasticSearch.  
    • Developing applications much faster: AWS services can be used for quickly building your application and bringing it to production in less time. It is much quicker than locating and implementing open-source packages or spending unnecessary time with the negotiation of proprietary license contracts.  
    • Matching the cost of service with its use: All the services from AWS are delivered in usage-based, on-demand and no commitment pricing manner. Use of AWS services for your applications ensures good economic outcomes for your applications for matching the cost with its benefits.  
    • Building more scalable applications: All the services from Amazon are designed for running at scale. In case your application needs large amounts of particular AWS products, the designing of the services will allow it to scale to the level of your requirements.  
    • Utilizing the experience of Amazon itself: A lot of the AWS products were created originally for the e-commerce platform of You have the confidence that all the AWS products you use are tested in the toughest of e-commerce environments.  

    Hope that now you have a basic understanding of the products provided by the Amazon Web Services and how you can use it for your own use. You can get more information on AWS through the AWS Certification course of KnowledgeHut.
