Architecting for the cloud aws best practices whitepaper 2020


For several years, software architects have discovered and implemented several concepts and best practices to build highly scalable applications. Today, these concepts are even more applicable because of ever-growing datasets, unpredictable traffic patterns, and the demand for faster response times. This paper reinforces and reiterates some of traditional service-oriented architectural concepts and discusses how they may evolve in the context of cloud computing. It will also discuss some unprecedented concepts such as elasticity that have emerged due to the dynamic nature of the cloud.

In a traditional computing environment, a company needs to provision capacity based of their best guess of a maximum peak traffic for instance - Black Friday. Which means that for extended periods of time, a vast majority of your capacity is essentially wasted. This is more or less why Cloud Computing was born - you get to use other's in AWS case - Amazon's extra capacity for your own purposes. Servers, databases, storage etc.

Horizontal scaling is best suited for stateless applications. A stateless application is an application that doesn't need the knowledge of previous request sent to this app, and as such - doesn't store the session information. If you're familiar with functional programming - a stateless application is essentially a pure function, always providing the same output given the same input.

Distributing the workload to different machines is easier said than done, there are two main approaches:. Alternatively, you could use Amazon Route 53 a DNS service to implement a DNS round robin, but this is not an elastic solution and comes with its limitations. You can still make a portion of these architectures stateless by not storing anything that needs to persist for more than a single request in the local file system.

You could use HTTP cookies to store session information but not only cookies need to be sent with every request, they can also be tampered with on the client side.

A recommended approach would be to store a unique session identifier in an HTTP cookie and storing more detailed user data on the server side. Storing the data on the server creates a stateful architecture so the common solution is to store this information in a database a DynamoDB is a great choice. If you need to handle large files, they should go into a storage layer such as Amazon S3 or Amazon EFS, which will help you avoid stateful components. There are applications out there that are specifically designed to run on a single machine for instance - real-time multiplayer games which require extremely low latency.

If you're developing an application like this - you don't want to spread the traffic to a random horizontally scaled instance. That ensures that as long as they keep playing - they won't be moved to a different physical machine. In other cases, you might want to implement client-side load balancing. It introduces extra complexity but might be necessary sometimes. In a traditional infrastructure environment you end up buying physical servers, installing them in a data center and manually ssh'ing into them to upgrade packages etc.

Not only it's expensive, it can also cost you your entire business if something were to happen to those machines. With AWS you end up treating servers and all other components as temporary resources, provisioning them only when necessary.

In order to be able to quickly provision multiple identical or highly similar resources you can use:. Bootstrapping - a script that you configure when provisioning an EC2 instance for example.

It's going to be executed once you launch the instance and it's possible to provide configuration details that vary between different environments staging and production for instance. This approach is generally faster than bootstrapping an instance and allows to quickly an reliably launch additional resources by essentially "cloning" an instance. It's possible to configure an instance and save its configuration to create an AMI Amazon Machine Image - afterwards you can use it to launch as many instances as you want.

There's also a hybrid model where some parts of the configuration are captured in a golden image, while others are configured dynamically through bootstrap scripts. AWS Elastic Beanstalk follows this model - it allows you to use AMIs to start up a new service as well as run bootstrap actions through. Infra can and should be stored as code and version controlled. With AWS CloudFormation templates it's possible to create and manage resources and update them in an orderly and predictable fashion.

This simplifies reusing architectures, as well as extending existing ones which is highly useful for larger organisations. Traditionally, someone had to manually react to incidents in order to increase storage capacity, deploy additional servers etc. With AWS, it's possible to automate those steps away.

The security labs are documentation and code in the format of hands-on labs to help you learn, measure, and build using architectural best practices. The labs are categorized into levels, where is foundational, is intermediate, is advanced, and is expert. Quests are designed to collate a group of relevant labs and other resources together into a common theme for you to follow and learn. Intro 2.

This Lens is closest to my area of expertise and therefore it is good time to write blog about it. As for my background, I am usually working in Nordic projects which generally has less data and smaller team sizes than the projects that AWS architects base most of their viewpoints in the document on. This blog is a commentary to the Analytics Lens document and will be highlighting things that I disagree with or strongly agree. Many of the disagreements are related to AWS having quite large projects as a reference versus in relatively small projects that are common in the Nordics. For example, AWS is selling Glue in many cases where it is too heavy for the data amount and even Lambda function could do the necessary transformations with much smaller costs. On the other hand, in the document there are many good points with which I agree, such as using columnar formats in S3. But the blog should be understandable without prior knowledge of Well-Architected Framework.

Companies in every industry are eager to leverage the benefits of the cloud and leave data center management and legacy technologies behind. As cost optimization and increased scale drive cloud adoption from the inside, the need to stay competitive to keep pace with market changes drives it from the outside. Within the enterprise, the rush to deliver cloud solutions quickly often results in underestimated migration timelines.
