The question no longer is should I migrate to cloud, it is - How?
When we say cloud migration, it commonly refers to migrating your existing infrastructure to cloud, generally using Infrastructure as a Service (IaaS) models offered by AWS, Microsoft Azure or IBM. It can also be combined with Platform as a Service (PaaS) models offered by IBM Bluemix or Pivotal Cloud Foundry, which generally offer faster time-to-market with pre-packaged frameworks and application services.
For organisations, the ultimate objective behind cloud migration is to update every facet of their business operations by harnessing the full potential of services based on the cloud, like big data & analytics, machine learning, etc. Although it’s incredibly easy to use these services, migrating the legacy infrastructure to the cloud and building a robust and secure environment around it, takes some doing. The questions, therefore, that often plague companies while considering cloud migration are:
- Will my cloud service provider offer me ample amount of archive and block storage?
- How will I know if my system is being configured with the right amount of RAM?
- What if I have to make an awful lot of changes to my code and applications?
At Bluepi, we believe that God lies in the attention to details. We consider each aspect of your existing infrastructure: current interface complexities, the life expectancy of the architecture and applications. We also factor in important points like latencies required, SLAs, integrations, overall workload analysis, type of users, maximum memory, operating system, network load balancing, interface cards, clustering, database versions and much more. We also understand the importance of virtualization as it can save you an enormous amount of money by avoiding overheads like expensive hardware, licenses, and associated maintenance costs.
BluePi meticulously plans from the outset and takes everything into consideration, including your budgetary issues, by chalking out the best hosting and migration strategy for you like we did for an Online Health Product Provider, HealthKart, when they decided to take their applications to cloud . Those of you bound by the laws and agreements, need not worry, as well. Most cloud service providers have their data centers in multiple regions allowing you the freedom of choosing the right one for you. Here are a few things that we help businesses understand, well before devising their migration strategy.
Understanding the cost factorSince one-size doesn’t fit all, BluePi takes care to analyze the following aspects before suggesting the right cloud migration strategy for your business:
- Current cost of running on-premises servers
- Costs involved during transition
- Cost involved post-transition to cloud, considering scalability
- Cost of upskilling your IT staff to work with the cloud setup, post migration
Bandwidth & Scalability Mapping
It is critical to understand what is the actual bandwidth required – especially since costs involved in a cloud setup hinges on this very aspect. Also, you need to have a sense of scale that your business is going to achieve, over time, to be able to accurately plan your migration to the cloud. Here are a few things to consider:
- The actual bandwidth required
- The average bandwidth to peak bandwidth ratio
- Costs incurred if the infrastructure needs to be scaled
It is a crucial aspect – whether on-premises or on cloud. Businesses need to put in place a proper disaster recovery plan, during migration, as well as post-migration. They also need to consider if they have the right data backup plan in place, considering their cloud environment – public cloud, private cloud or hybrid, and their overall cloud stack. From power outages to natural disasters, all the risks should be thoroughly evaluated before putting them together in a plan and addressing the downtime and recovery options. Datacenter location, backup and storage options, peak power requirements, costs involved - all play a major role in arriving at the optimum disaster recovery plan.

Cloud services often come with security features like encryption, access controls, etc. that play a major role in deciding your cloud migration strategy like, leading QSR brand, Yum, had a lot of customers sensitive data which needed to be secured and integrated with other systems for a seamless cloud migration . The type of cloud setup you choose – public vs. private vs. hybrid - also hinges on security considerations. Do you have a lot of sensitive data that you’d want stacked up in-house? Private cloud or a hybrid setup might be the better options in this case. However, if you prefer ease of use and best economies of scale while being cost-effective, then, public cloud is the way to go.The phrase Old is Gold does not apply everywhere. Get on Cloud, get moving ahead!
