Cloud based software architecture

This means that almost all of the principles of good architectural design still apply for cloud-native architecture. In this post we set out five principles of cloud-native architecture that will help to ensure your designs take full advantage of the cloud while avoiding the pitfalls of shoe-horning old approaches into a new platform.

Broadly speaking, the decision of whether or not to adopt managed services comes down to portability vs. Crudely, the managed services that you might consider today fall into three broad categories:.

However, practical experience has shown that most cloud-native architectures favor managed services; the potential risk of having to migrate off of them rarely outweighs the huge savings in time, effort, and operational risk of having the cloud provider manage the service, at scale, on your behalf.

Cloud-native architectures have their origins in internet-facing services, and so have always needed to deal with external attacks. Therefore they adopt an approach of defense-in-depth by applying authentication between each component, and by minimizing the trust between those components even if they are 'internal'.

As a result, there is no 'inside' and 'outside'. Cloud-native architectures should extend this idea beyond authentication to include things like rate limiting and script injection. Each component in a design should seek to protect itself from the other components. This not only makes the architecture very resilient, it also makes the resulting services easier to deploy in a cloud environment, where there may not be a trusted network between the service and its users.

The principles described above are not a magic formula for creating a cloud-native architecture, but hopefully provide strong guidelines on how to get the most out of the cloud. If you would like to learn more about the topics in this post, check out the following resources:.

At a high level, cloud-native architecture means adapting to the many new possibilities—but very different set of architectural constraints—offered by the cloud compared to traditional on-premises infrastructure. For instance, provisioning a replacement server can take weeks in traditional environments, whereas in the cloud, it takes seconds—your application architecture needs to take that into account. As an added benefit, moving and adapting architectures for cloud gives you the opportunity to improve and adapt them in other ways, and make them better able to adapt to the next environmental shift.

Change can be hard, but as evolution has shown for billions of years, you don't have to be the best to survive—you just need to be able to adapt. Infrastructure as code IaC lets you make changes to your environment in a way that can be tested, automatically applied and be audited. This sets the stage to handling massive growth in demand for your applications. Get started Contact Sales.

Tom Grey. New whitepaper: Serverless at scale With education and planning, our serverless platforms can handle nearly any workload. Consider the high level elements that we as software architects are trained to consider: The functional requirements of a system what it should do , e. Principles for cloud-native architecture The principle of architecting for the cloud, a. Traditional architecture tends to optimize for a fixed, high-cost infrastructure, which requires considerable manual effort to modify.

Traditional architecture therefore focuses on the resilience and performance of a relatively small fixed number of components. Therefore, cloud-native architecture focuses on achieving resilience and scale though horizontal scaling, distributed processing, and automating the replacement of failed components. The entire cloud architecture is aimed at providing the users with high bandwidth, allowing users to have uninterrupted access to data and applications, on-demand agile network with possibility to move quickly and efficiently between servers or even between clouds and most importantly network security.

What is cloud computing technology architecture? The various components of Cloud Architecture are: On premise resources Cloud resources Software components and services Middleware The entire cloud architecture is aimed at providing the users with high bandwidth, allowing users to have uninterrupted access to data and applications, on-demand agile network with possibility to move quickly and efficiently between servers or even between clouds and most importantly network security The various cloud based services have their own distinct and unique cloud architectures: Software as a Service SaaS involves software hosted and maintained on internet.
