Migrating data center infrastructure to the cloud offers businesses many significant advantages. Once the decision has been made, it is important to keep in mind that a massive undertaking such as this runs the risk of setbacks if not executed carefully and correctly. In many companies, executive leadership is already hesitant to make such a large change, so ensuring that the entire migration is completed without an outage is essential for continued buy-in. This blog offers insights into what steps can be taken before and during the actual migration to help keep the business operating without interruptions.
Migrating in-house data center infrastructure to the cloud is not something that a company should rush into. This is a significant undertaking that needs to be properly planned to avoid problems. Depending on the size and scope of the migration, it may require months of preparation before cutting over.
During the planning phases of this process, IT teams will have to split their attention between maintaining their existing in-house systems and preparing for the move to the cloud. Having a qualified consultant to take on the bulk of this work will be essential to avoid problems in the current systems and mistakes in setting up the new cloud infrastructure.
When systems are moved from an in-house data center to the cloud network, traffic must travel out through the internet (either through the public internet or dedicated circuits) to reach the cloud infrastructure. This is a major adjustment, and will likely require lots of steps to be taken to accommodate the move:
Increased data capacity – Each facility that will require significant access to the new cloud systems will need to ensure they have sufficient capacity to avoid any type of bottleneck.
Redundancy – If there is only one circuit for traffic going to and from the cloud, that is a dangerous single point of failure. Having multiple circuits provisioned is essential for redundancy. It’s also a good idea to have these circuits managed by separate ISPs.
Managing traffic – Another thing to consider is to evaluate when certain types of traffic are using the circuits. For example, it may be possible to perform file restores or backups only after hours to help minimize traffic levels during peak times.
One of the best things that can be done to minimize business impact is to prepare the cloud infrastructure ahead of time and complete extensive testing before cutting over the service. For example, setting up a corporate email system on the cloud would be step one. Step two would be to perform every action that is currently done on the in-house system on the cloud to make sure it works smoothly. For some applications and systems, it may even be possible to replicate activity from an in-house system on the cloud to ensure it is working. Only after extensive testing has been done, would production processing be moved fully to the cloud infrastructure.
Perhaps the most important thing that a business can do when migrating their data center infrastructure to the cloud is to work with an experienced consultant. Major migrations like this are simply not something that most people—even experienced IT professionals—have done in the past.

When large companies migrate their in-house systems to a cloud environment, it is usually done slowly over time. Attempting to migrate dozens or even hundreds of different systems, all at once, will lead to production outages and other issues. This is in addition to the fact that it would mean decommissioning existing systems well before their scheduled end of life.Explore
In and of itself, data doesn’t hold any special value. Instead, the insights drawn from data analytics uncover information and metadata about events, products and historical facts. And while that has added a lot of value in our analysis, occasionally that data contains confidential aspects such as personally identifiable information (PII data - social security numbers and mailing addresses), protected health information (PHI data - health history and medical allergies), and secure fiscal data. As data engineers, it is our ethical and legal responsibility to protect that information.Explore

With the sweeping spread of COVID-19, enterprises have seen an unprecedented level of disruption to their daily operations. As governments struggle to contain the escalation of the virus, many countries have begun to enforce either nationwide lockdowns or strict curfews to minimize person-to-person contact via social distancing measures.Explore
Technology is an essential tool for every company today. Unfortunately, most companies take a reactive approach to manage their IT systems. When they find that they need something to accomplish a business goal, they purchase it and go from there. This lack of a digital strategy is the most expensive and least effective way to manage this critical department.Explore
