Why You Should Embrace Database Virtualization
+1 Vote Up -1Vote Down
This article addresses the benefits provided from database virtualization. Before we proceed however, it is important to explain that database virtualization does NOT mean simply running a DBMS inside a virtual machine.

Database Virtualization, More Than Running a DBMS in a Virtual MachineWhile running a DBMS in a VM can provide advantages (and disadvantages) it is NOT database virtualization. Typical databases fuse together the data (or I/O) with the processing (CPU utilization) to operate as a single unit. Simply running that single unit in a VM does not provide the benefits detailed below. That is not database virtualization that is merely server virtualization.
An Example of the Database Virtualization ProblemSay you have a database handling banking and I have $10MM in the bank (I wish). Now let’s assume that the bank is busy, so it

Lack of Business Visibility Cripples Traditional SQL DaaS, Drives NewSQL
+0 Vote Up -0Vote Down
More and more public cloud companies are moving to managed cloud services to improve their value-add (price premium) and the stickiness of their solution. However, the shift to a database as a service (DaaS) severely reduces the DBAs visibility into the business, thus limiting the ability to hand tune the database to the requirements of the application and the database. The solution is a cloud database that eliminates the hand-tuning of the database, thereby enabling the DBA to be equally effective even with limited visibility into the business and application needs. It is these unique needs, particularly for SQL databases, that is fueling the NewSQL movement.
DBAs traditionally have insight into the company, enabling them to hand tune the database in a collaborative basis with the development team, such as:

MySQL Clusters on Amazon EC2 - verified AMIs
+1 Vote Up -0Vote Down
We regularly receive questions from our user community with regards to which AMIs to use when deploying database clusters on Amazon EC2.

As part of our ongoing development work on the Severalnines Configurator and ClusterControl, we have recently done some testing on deploying MySQL Cluster on EC2 using Severalnines on three different AMIs. We thought we should share the results of these tests, hence the reason for this week's blog!

If you would like to test such a deployment yourself, feel free to use the parameters and guidelines below to do so. You can also check out these new videos to see

Do you need an elastic database?
+0 Vote Up -0Vote Down
Not every company or application needs an elastic database. Some applications can get by just fine on a single database server, rendering database elasticity moot from their perspective. To make this determination, simply ask yourself:
1. Will I need more than a single database server?Look at your current load and your projected growth and ask yourself whether it will exceed the capacity of a single server. If it doesn’t now, nor will it in the future, then you don’t need an elastic database.
2. Will my load fluctuate sufficiently to warrant the investment in elasticity?If your database requirements won’t experience fluctuations in demand—e.g. daily, weekly, monthly, seasonal changes in the number of servers required—then elasticity isn’t important. For example, if you have a social networking application that requires 2 database nodes 24x7, but peaks at 10

Cloud Elasticity & Databases
+0 Vote Up -0Vote Down
The primary reasons people are moving to the public cloud are: (1) replace capital expenses with operating expenses (pay as you go); (2) use shared resources for processes like back-up, maintenance, networking (shared expenses); (3) use shared infrastructure that enables you to pay only for those resources you actually use, instead of consuming your maximum load resources at all times (pay-per-use). The first thing you’ll notice is that all 3 cloud benefits have their basis in finances or the cloud business model.
We will focus in on #3 above: Pay-Per-Use. The old school model was to build your compute infrastructure for the maximum load today, plus growth over the life-cycle of the equipment, plus some buffer so the systems don’t get overloaded from spikes in usage. The net result is that your average usage might run 10% of the potential for the infrastructure you mortgaged

ScaleDB: Shared-Disk / Shared-Nothing Hybrid
+0 Vote Up -0Vote Down
The primary database architectures—shared-disk and shared-nothing—each have their advantages. Shared-disk has functional advantages such as high-availability, elasticity, ease of set-up and maintenance, eliminates partitioning/sharding, eliminates master-slave, etc. The shared-nothing advantages are better performance and lower costs. What if you could offer a database that is a hybrid of the two; one that offers the advantages of both. This sounds too good to be true, but it is fact what ScaleDB has done.
The underlying architecture is shared-disk, but in many situations it can operate like shared-nothing. You see the problems with shared-disk arise from the messaging necessary to (a) ship data among nodes and storage; and (b) synchronize the nodes in the cluster. The trick is to move the messaging outside of the transaction so it
