Cloud native vs. Cloud agnostic – What’s the conundrum behind the hype

Speed seems to be the imperative behind digital. We can see huge, successful solution providers moving from rigid monolithic structures to loosely coupled service based architectures. Cloud based solutions together with API-based communication and container-centric applications seem to have helped in this shift. And they have surpassed the initial hiccups. For some time, cloud providers, especially the most famous ones such as Amazon, Microsoft Azure and Google Cloud, have driven business processes globally. As the technology continues to mature, the company’s business processes are now questioning which cloud platform is more efficient, what could be easily maintainable, which option is potentially more beneficial in the long term. At this juncture comes the debate: cloud native vs cloud agnostic. This is the point where companies decide whether to stick to one vendor or to be omni-present on all clouds.

Cloud Native: See the power of sticking to one provider

When a beginner like me tries finding the meaning of cloud nativity I get tons of different answers and end up as confused as I was when I started the process. Cloud platforms require applications to run in a distributed nature with systems that are scalable, automatic and fault tolerant, but is that it? Or is there something more to it? According to a leading author on the topic,1 being cloud native is to surrender yourself to a platform and build for it. This means your application takes advantage of the strengths of the underlying platform instead of trying to be present in all clouds.

Pros: Cloud native services have better performance, better efficiency and lower costs. One can inherently use auto scaling and load balancing features of cloud offerings by providers such as Amazon, and Google.

Cons: Cloud native would mean we end up using native APIs, but when a client has to move to a different cloud provider, it can involve a lot of code rewriting. Moreover, if the cloud provider changes the services during upgrades, the application will also have to react accordingly and this can be both time consuming and costly. So does being cloud native efficiently solve your business objective?

Cloud Agnostic: Free yourself from vendor lock-in

Agnostic in the IT context would mean to be interoperable and it can refer to either software, hardware or even business practices. Thinking on the same lines, cloud agnostic means moving from one cloud to another without much impact to the IT systems and business processes. To put it in mere technical terms, each of the cloud services say the infrastructure, platform and software, could be taken from different service providers and yet must not have impact the services provided. So in a way the data should be portable and the applications should be platform agnostic. Containerization2 helps in being cloud-agnostic, it enables building the platform within the container and the applications can be run anywhere.

Pros: For clients working on multiple clouds, cloud agnostic service platforms will provide the required consistent and standard performance in every environment.

Cons: However, hopping between cloud providers will come with its own cost and complexities. It could mean the client is not using the complete capabilities of one vendor. Performance can also take a hit due to internal design differences of each vendor. Moreover, logging and monitoring is really difficult with multiple cloud providers. They may not really provide a way to maintain and aggregate logs across platforms. So is being cloud agnostic worth the costs associated with it?
