Ever-evolving technologies are transforming the way Data Centres (DC) operate. Many organisations have built their own DCs with huge investments on IT infrastructure that requires proper maintenance and skilled resources. As a step towards transformation, most organisations have introduced virtualization of servers, networks, and storages in their DCs.
In the subsequent step towards the next generation DC architecture, IT leaders are exploring converged/ hyper-converged infrastructure and Software Defined Data Centre (SDDC) which drives most of the DC activities like provisioning and managing resources, monitoring and policy-driven automations through the orchestration layer. Though SDDC seems to be offering powerful capabilities, the evolution of this technology may take some more time before organisations adopt it. Also, the available management tools and skills required for managing SDDC are restricting the adoption levels of this technology.
Launching new product lines and innovation are a must for any winning organisation which require efficient and agile technology support. Horizontal or vertical scaling of the infrastructure in the traditional data centres requires to go through lengthy procurement and DC server induction processes. At times, though software applications are ready to get deployed, delays in infrastructure readiness becomes the main challenge for IT teams. CIOs have to face these challenges head-on and provide agile solutions for businesses with lower cost and without compromising on any of the security best practices and standards.
While it is very difficult to predict the future of the IT industry, one thing that can be clearly witnessed in the path towards IT transformation is the increased adoption of the cloud technology.
Cloud computing is an evolving paradigm offering on-demand self-service, broad network access, resource pooling, elasticity and managed services with IaaS, SaaS, PaaS as service models and public, private/community & hybrid as deployment models.
Debate on public Vs private cloud is evergreen and never-ending. Scalability, elasticity, and agility are definitely some of the advantages of the public cloud. However, compliance concerns due to its multi-tenant structure and national boundary limitations while hosting data are encouraging organisations to opt for private cloud path or confine to their traditional DCs.
Private cloud, with its single tenant approach, promised the same advantages as that of public cloud in terms of scalability, flexibility and self-service with an added advantage of answering all the security/compliance concerns associated with the public cloud. However, when actually delivering the same, it is falling short of expectations in certain areas. Private cloud is set up for one organisation, unlike public cloud. As it is serving a single organisation, there is no diversity of peak loads available. Without this diversity, sizing of private cloud should happen considering the spikes. It puts constraints on scalability and results in an expensive proportion. Private cloud requires to re-architect its DC infra and adopt additional management tools.
For organisations with large existing DCs, it may not be an advisable option to move out/ migrate completely to cloud owing to the costs involved in migration, challenges in adoption of new cloud technologies, building new skill sets, etc. Hybrid may be the ideal choice for organisations that require some of their applications to be on premise. While choosing the service and deployment model for any application stack, it is very important to analyse the application interfaces and the number of hops that cloud hosting may increase.
Many organizations know the benefits of public cloud, but are hesitant to use them due to multi-tenant approach. Virtual Private Cloud is another option that offers a single tenant environment set up in a public cloud. This will work as an extension to your own DC and may be another way of combining cloud and on-premises computing.
With a multi-cloud approach, you will have multiple cloud providers trying to differentiate themselves with different features. Handling these variations will require changes in the application solution. When adopting this strategy, opt for cloud comparison and estimate the costs to find the best-fit cloud provider for an application stack.
Each option of cloud deployment has its own pros and cons. Organisations have to think of their IT landscape and their future needs to adopt relevant cloud services and deployment strategy. Moving the data and applications to cloud without proper strategy will result in subsequent maintenance issues.
