Cloud Computing is becoming more and more a recurring topic in IT industry meetings when it comes to data storage or high availability of resources. With that in mind, we have developed a guide for you to be prepared for your next meeting. In this article, you will understand all the benefits that this type of solution can add to your company and check the key steps needed to understand how to do the migration to Cloud and what is the best type for your company.
Recent statistics estimate that by 2020, more than a third of data will travel through Cloud infrastructure. And these are conservative estimates.
With each passing day Cloud Computing is proving to be an attractive alternative for companies that have diverse infrastructure and development needs.
But when is the right moment to migrate to the cloud? There are several reasons that can lead to this decision, here, we highlight some of the main ones:
Depending on the time of the company, there are different approaches to a successful migration. Here are 2 different ways to get your business onto the cloud:
Lift and shift
In this approach, processes are migrated to the cloud environment with little or no change to the new environment. Changes are made only when strictly necessary and on time. The tools in the on-premises environment are widely used in this new environment. Native features of the cloud environment are underutilized. This approach is more direct and may not demonstrate all the advantages of adopting a cloud environment, as well as the economic advantages that the cloud can offer.
Automation for Cloud Computing
In this model, the processes are modified in order to obtain the maximum benefits of the automation tools of the cloud environment. During the migration process, we take the opportunity to review processes, excluding the unnecessary and reviewing key points such as: Security, High Availability (HA) and the performance of others, which effectively impact the costs of using the cloud environment. This is the ideal model for companies that want to avoid a rapid process of migration and adopt new technologies without a transition period.
The decision to migrate to the cloud is not enough. There is also the need to decide where to migrate to, that is, to a public or private cloud, or to adopt a hybrid environment.
To do so, you should evaluate important questions such as:
The first step to a successful migration is to define where to go, as we saw in the previous topic. From this, we can begin the process of mapping the current environment: existing contracts, hardware, connectivity and existing software.
Thinking about the most common scenario, where companies already have an existing infrastructure, we can organize the information gathering the following:
Current contractual obligations
Review the terms and conditions associated with the data center you are leaving, including termination clauses and penalties. This indicates what obligations you have when you leave the current data center.
Survey your entire infrastructure. Such information is important as you will know which equipment still has an average useful life, which is near the end of the warranty and which are effectively in EOL (end of life).
Make a spreadsheet with information from Domain Controllers, Application servers, DB servers, routers, switches, firewalls, Web filters, Web server farms, load balancing devices, modems, edge or DMZ servers, uninterruptible power supplies (UPSes), power distribution units PDUs), backup devices, etc. Each of the equipment must be inventoried with:
This survey may have surprises, including critical hardware you did not realize you had mapped or old servers that still serve critical functions. Be thorough.
The connectivity resources survey includes all non-tangible network features and configurations that need to be moved, replaced, or removed with the current infrastructure migration. Such resources may include:
After surveying hardware and connectivity, you need to identify all applications running on physical and virtual machines, as well as any external servers that communicate with computing resources in your data center. That includes:
Factors that influence a successful migration:
How much effort are you willing to put into the migration? An application survey gives you an idea of how your data center is connected both internally and externally. This provides a map of all the connections that need to be migrated together with your data center.
The data center survey provides all the information you need for robust planning for migration to either another data center (private cloud) or a public cloud. It provides the mapping of the physical and network infrastructure that your company is based on, as well as the applications that currently run on that infrastructure.
This document helps you create a more efficient migration strategy as well as identifying risks that your organization may face during the process.
An Inventory is one of the first (and not the only) items that must be created to begin the migration process.
