The Promise of Multi Cloud
Several reports by industry think tanks have indicated that multi-cloud adoption is on an all-time high. IDC says that 2017 will witness more than 85 percent of enterprises committing to multi-cloud architectures. A recent Dimensional Research survey of more than 650 IT decision-makers found that 77 percent of businesses are planning to implement multi-cloud architectures in the near future.
But really, what is multi cloud?
An overhyped fad? Or a brilliant technology?
In this post, we look at what are the advantages of multi cloud and why enterprises should construct a multi-cloud strategy.
Multi vs Hybrid
Multi-cloud is almost always confused with hybrid-cloud in the business world. Let’s clear that for once and for all.
Multi-cloud is when businesses leverage multiple cloud service providers such as AWS, Azure, OpenStack, etc, to power multiple applications, and also includes on-premise infrastructure. On the other hand, hybrid-cloud is about a bridge that connects multiple deployment platforms, such as public cloud, private cloud, dedicated and on-premise servers.
Advantages of multi-cloud
It’s not that hard to understand why enterprises are scrambling to add multi-cloud in their infrastructure arsenal, given its numerous benefits:
- Match the right cloud with the right requirement.
For example, using public clouds such as AWS and Azure for quickly scaling up and down to meet customer demand during a sale period, while banking on private cloud for proprietary applications.
- Avoiding vendor lock-in
With only one vendor to rely on, you are tied up to specific protocols, standards and tools, that might not work in your favor. Migrating to another cloud may prove to be costly too.
- Improve disaster recovery and geo-presence
Having multiple cloud centres in different countries helps in reducing risks of downtime and also leads to lower latency.
New technologies in cloud – Serverless and Containers
Upcoming technologies in cloud such as containers and serverless are only making the deal of multi-cloud sweeter. If moving application from one cloud to another is a challenge, behold containerization. If you want to burst to cloud only for specific function deployment, then serverless is the key. Let’s look at these two in some more detail:
What if the developer wants to move the application from AWS to Microsoft Azure or vice versa, in a multi-cloud setup? That’s where container technology steps in. Containerization is an OS-level virtualization method to deploy and run distributed applications without launching an entire VM for each application. Instead, multiple isolated systems, called containers, are run on a single control host and access a single kernel.
Serverless computing (Function as a Service) executes function code that developers write using only the precise amount of compute resources needed to complete the task, slashing down costs.
Enterprises need a multi-cloud strategy
Isn’t multi-cloud a great approach? By adopting a multi-cloud strategy enterprises can cherry pick the best technologies and services from different cloud service providers to create the solution that best fits their needs. And that’s why enterprises are lining up for it.
While adopting multi-cloud, it is necessary to have a multi-cloud strategy in place, that covers governance, applications and data, and platforms and infrastructure.
Having a multi-cloud strategy helps:
- Tamp down Capex
By using cloud technology, enterprises reduce infrastructure costs and shift to modest operational costs.
- Ensure security
Security is a given as the cloud service providers are zealous about data protection and ensure that stringent perimeter security measures are taken.
- Finalize cloud orchestration solution
Multi-cloud comes with its set of challenges. Therefore, it is vital to opt for a multi cloud orchestration solution that provides automation capabilities to effectively consume and govern cloud resources.
Multi-cloud is definitely the way forward for enterprises that want to undergo a digital transformation. However, before rushing into things, it is essential to formulate a strategy, for multi-cloud technology to deliver on its promise.
