Amazon Web Services (AWS) has announced a recent spike in demand for its database migration services.
The company's chief Andy Jassy made this revelation earlier this month, tweeting the following: "16K database migrations via AWS Database Migration Service in 2016...2K in last month since #AWS #Reinvent. DB freedom is a powerful thing." So, according to Jassy, AWS has migrated some 2,000 databases for customers since November 2016. In comparison, they migrated 16,000 databases in all of last year. What's even more impressive is that experts believe these numbers will continue to rise as more and more customers shift their focus to the cloud.
Data migration, as the name suggests, is a service that involves transferring data between two or more storage devices and/or file formats. It's a highly important consideration for any system upgrade or consolidation. According to Wikipedia, data migration is typically performed "programmatically" so it results in automated migration; thus, eliminating -- or at least reducing -- manual labor requirements.
So, what's the purpose of data migration? Professionals and individuals choose data migration services for a variety of reasons, one of the most common being storage equipment replacement. If your company is upgrading its storage servers, you'll need somewhere to store the data so it doesn't get lost. With data migration services, such as those offered by AWS, you can safely migrate your data to new storage devices without fear of losing it. Other reasons for data migration services include storage equipment maintenance, upgrades, application migration, website consolidation, and data center relocation.
Of course, data migration is a time-consuming, tedious and methodical process, which is why many professionals prefer a service like the one offered by AWS. Before the data can be migrated, the old data must first be mapped to the new system using a design for data extraction and loading. Doing so associates the old data formats to the new system's formats and any requirements it may have. Once loaded on the new system, data is then verified to determine whether or not it was accurately translated. During this procedure, the service provider may also run a parallel run of both the old and new systems to ensure it functions as intended and without any errors.
Both automated and manual data cleaning is often performed in conjunction with a data migration services. This serves several purposes, including improved data quality, identify and eliminate redundant or otherwise unnecessary information, and to match the requirements of the old system with the new system.
There are several "phases" in a typical database migration service, some of which include design, extraction, cleansing, load and verification. Each stage plays an important role in the final product. If a service provider fails to complete one of these phases, the end result could be poorly migrated data with errors or other discrepancies.
Many companies offer database migration services, though Amazon Web Services (AWS) continues to dominate the field. As noted by the company's chief executive, it was migrated databases for more than 2,000 customers since November 2016. So, what makes AWS such a popular choice for database migration services?
For starters, the service allows for quick and easy database migration from on-premise data centers to Amazon Web Services (AWS). If a company has data stored locally, on its premise, it can use AMS to migrate to the cloud. And being that cloud computing it such a hot topic among IT professionals right now, it's no wonder why AWS continues to dominate the field of database migration.
Even so, AWS remains the undisputed leader in cloud computing as well. Reports indicate that the world's largest online retailer pulled in some $3.23 billion in net sales in the fourth quarter of 2016 for its cloud computing services. To put those numbers into perspective, that's roughly 55% higher than what it pulled during this same period just one year prior.
Some market experts believe, however, that Amazon may struggle to maintain such a dominant lead in the cloud computing field. With other big names like Microsoft and Google edging investing heavily in cloud computing services, Amazon can expect some heated competition in the months and years to come. Will this competition be enough to dethrone AWS as the undisputed leader of cloud computing? Only time will tell, but consumers can expect to see more cloud offerings, both from Amazon and other service providers, in the near future.
"AWS Database Migration Service helps you migrate databases to AWS easily and securely. The source database remains fully operational during the migration, minimizing downtime to applications that rely on the database. The AWS Database Migration Service can migrate your data to and from most widely used commercial and open-source databases," wrote AWS when describing its highly popular database migration service. "The service supports homogenous migrations such as Oracle to Oracle, as well as heterogeneous migrations between different database platforms, such as Oracle to Amazon Aurora or Microsoft SQL Server to MySQL"
Another key selling point of AWS database migration is that it has virtually zero downtime. For businesses, downtime -- even hours and not days -- can spell disaster. You won't be able to accept new orders, fulfill existing orders, or perform any other operation that requires access to your data. AWS has acknowledged this concern, which is why it offers database migration services with almost no downtime at all. All migration changes are continuously replicated so the source remains functional during the operation.
