AWS sees growth in database migrations

AWS chief executive Andy Jassy speaks during the 2016 AWS re:Invent conference in Las Vegas.


Public cloud market leader Amazon Web Services (AWS) offers a lot of services — 83 by my count. Some of them are more popular than others. Without question, the core EC2 computing service and S3 storage service are among the most popular. But then what?

AWS’ parent company, Amazon.com, doesn’t break out sales numbers for all of the AWS services. So instead AWS spectators have to lean on occasionally released, typically non-financial figures to get a feel for what’s being used.

On Friday AWS chief executive Andy Jassy shared new data on increasing use of the Database Migration Service (DMS), which lets organizations quickly and easily move databases from on-premises data centers onto AWS’ data center infrastructure. AWS first introduced it at its re:Invent conference in October 2015.

Since re:Invent 2016 at the end of November, customers have migrated 2,000 databases with DMS, and in all of 2016 there were 16,000 migrations, Jassy claimed in a tweet.

“DB [database] freedom is a powerful thing,” he wrote.

The numbers — which follow Amazon’s April 28 disclosure that in the year to date “more than 2,000 databases” had been migrated with DMS — show a clear spike, and they don’t appear to be directly attributable to any one enhancement announced at re:Invent 2016.

But Jassy’s comment about “freedom” is a bit more complex. With the help of the free Schema Conversion Tool, customers can use the Database Migration Service to take data from existing databases — SQL Server, Oracle, PostgreSQL — that cost lots of money and push their data into cloud-hosted versions. While AWS offers cloud implementations of all of those, AWS also runs its own Aurora managed relational database.

While adopting Aurora might mean freedom from Oracle and Microsoft databases, customers can simultaneously become shackled to Aurora, because, although it’s advertised as being 1/10 the price of “commercial databases,” it’s not open source. Which could make matters more difficult in the event that organizations elect to move their data elsewhere.

In any event, leaving aside the “freedom” bit, what we do know today is that usage of the Database Migration Service is increasing.

Samsung’s phone-as-desktop concept now runs Linux

Samsung's DeX is a clever way to turn your phone into a desktop computer. However, there's one overriding problem: you probably don't have a good reason to use it instead of a PC. And Samsung is trying to fix that. It's unveiling Linux on Galaxy, an app-based offering that (surprise) lets you run Linux distributions on your phone. Ostensibly, it's aimed at developers who want to bring their work environment with them wherever they go. You could dock at a remote office knowing that your setup will be the same as usual.

It's not quite the same as your typical Ubuntu or Debian install. Linux on Galaxy launches through an app, and it's using the same kernel as Android itself in order to maintain performance. And it almost goes without saying that you'll really want a DeX setup, since most Linux apps are expecting a large screen, mouse and keyboard.

As it stands, you'll have to be patient. Linux on Galaxy isn't available right now -- you can sign up for alerts, but it's not ready for public consumption. Even so, this is good evidence that Samsung thinks of DeX as considerably more than a novelty feature. It may be a long, long while (if ever) before many people are using their phones as desktops, but Samsung is willing to gradually build up its ecosystem and eventually give you an incentive to take a second look.
