Top Considerations Before Moving to a Hybrid Cloud
Everyone in the digital world is talking about the Cloud. Why are they? How are organisations making millions of dollar from it? The cloud is something which is not just a part of the trend but also a caterpillar for businesses. Why would someone go for establishing a data centre rather than choosing the same services provided by big cloud vendors at cheaper costs?
Allow these big companies to support your back end with their vast and well-established datacenters. It will save your extra spending on infrastructure, staffing, expertise, electricity costs etc.
There are various argot in the cloud world which you may be unaware of. Hybrid cloud is one of the idioms you’ll see. Let’s understand the basics first then we’ll move this discussion to hybrid cloud implementation and considerations.
What is Hybrid Cloud?
In simple words, a hybrid cloud is a mixture of public cloud and private cloud for providing computing solution for a business or other organisation related tasks. A public cloud, as I mentioned earlier about third party service providers- responsible for managing infrastructure, security and other aspects. But do remember one thing- data security is your responsibility.
While, a private cloud infrastructure is accessed by a specific organisation or just a few people. Sometimes, an organisation host their private cloud over on-premise infrastructure. Otherwise, they host it on a third-party’s infrastructure and only your organisation will be accessible to these use those resources. In a private cloud, companies get more control over resources than public cloud where most of the things are under vendors control. The only concern is that private cloud is expensive.
So, a hybrid cloud merges both of them for you. You can differentiate your cloud work such as data into two parts- one consist of highly sensitive data and other low- sensitive data. Now depending on your requirement design your framework for public and private cloud part and manage their security groups separately. What a fantastic approach- put your low sensitive data on the public cloud and higher sensitive data over private. But, it doesn’t mean your public cloud doesn’t demand security- save your data as much as possible from your end. You can implement various cyber security solutions to both the public and private environment of hybrid cloud.
Let’s go through a few critical considerations when migrating to the hybrid cloud approach.
Security and Risks:
The elastic cloud computing resources in public cloud assist organisations to test new applications on-premise infrastructure resources and host them quickly. Since private cloud infrastructure provides improved security- but it often doesn’t offer elastic resources. Here comes the hybrid cloud approach where sensitive data and application are governed internally, while insensitive parts can be hosted externally. So it’s your responsibility to carefully categorised components and address the security and risk measures with their successful compliance.
Carefully Select Cloud Service Provider:
Since various hybrid cloud vendors support workloads, it doesn’t mean you will always get extra services for the acquired platform. In today’s world, security is the primary concern of organisations due to increased cyber attacks and threats. So, before selecting your service provider, you should perform a proper background check and measure their performance log, because your vendor is also responsible for handling active attacks like DDoS. Check your vendor’s qualification such as ISO 27001 and HI-TRUST etc. Companies like Amazon has marked a good market presence by providing support to thousands of organisation. They offer various services for deploying your application and manage resources such as Elastic Cloud Compute, Lex, Polly, Glacier etc. One can join AWS Developer Certification to explore these products and effectively learn to develop their infrastructure to deployment model.
Since private cloud demands more expenses than the public cloud, so, carefully decide which part will fall under private and public. Service providers charge for used services. The billing raised from their end contains expenses for per hour use of resources. Always acquire only limited and essential resources because the scalable feature of the hybrid cloud allows you to scale up and down resources on demand.
With all these incredible features, hybrid cloud has made an inspiring presence in the market. It has estimated that it will cover a total market of $97.64 billion by 2023. The resource categorisation feature of hybrid cloud attracts more and more businesses to adopt this technology.
