Whether you are making a wholesale transition of all your IT service delivery to the cloud or just one mission-critical application, you need a plan. This is what many enterprises discover as they start on their cloud journey and for good reason. Establishing a relationship with a cloud provider and consuming their services is just the tip of the iceberg when it comes to making sure you are maximizing cloud efficiency and scalability when moving an entire data center or even parts of an it to the cloud.
A data center migration must start with very careful planning and a phased approach to execution, without causing a significant impact to business operations, service delivery, performance and data protection requirements. Following these steps to strategically plan any cloud adoption will help you realize the cost, scalability, time to market, and security and compliance benefits that cloud, and in particular multicloud, can offer.
Planning and Design:-
This phase requires you to answer some hard questions about your existing data and application workloads, as well as what you plan to do in the future. For example, do you need both cloud compute and storage resources for my data and applications? How do you want to segment resources in terms of subnets, DHCP blocks, or even separate cloud billing accounts? Who do you want to access the cloud services and what will be the security and compliance policies around those users? First, knowing where, how and by whom your IT services and applications are being used is a good place to begin.
Many companies see cloud interconnectivity as an after-the-fact conundrum, but if you think interconnection-first, then you can build a higher performing, scalable, secure and cost-effective interconnected-cloud infrastructure. Understanding if you are going to leverage existing MPLS or VPN corporate networks, direct, private cross connects or exchanges, or the internet for some or all of your cloud traffic should be looked at on a data and workload, case-by-case bases. As does the proximity of your interconnection between clouds, data, applications and users to ensure the best performance. Multicloud interconnectivity is a growing requirement among enterprises, where applications are deployed across multiple clouds to decrease IT spending, increase the quality of service delivery, or for redundancy to ensure business continuity (BC) and disaster recovery (DR). By 2020, 86% of companies will be interconnecting multiple clouds across multiple locations and over the next five years to realize a lower Capex.
