"To many this is no-brainer. Amazon wants to support the databases that its developer audiences want to use. This is simply a case of Amazon responding to user demand and oh-by-the-way making its cloud infrastructure more attractive to a specific target audience. Some say Postgres has gained traction since Oracle’s acquisition of MySQL via its Sun buyout a few years back."

We are doing a migration from Amazon RDS to EC2 with a customer. This, unfortunately, involves some downtime – if you are an RDS user, you probably know you can’t replicate an RDS instance to an external server (or even EC2). While it is annoying, this post isn’t going to be a rant on how RDS can make you feel locked in. Instead, I wanted to give you a quick tip.
So here’s the thing – you can’t stop replication on RDS read replica, because you don’t have (and won’t get) privileges to do that:
replica> STOP SLAVE; ERROR 1045 (28000): Access denied for user 'usr'@'%' (using password: YES)
Normally, you don’t want to do that, however we wanted to run some pt-upgrade checks before we migrate[Read more...]
As with all new open source software products, updates are a continuous process and we’ve been busy since the launch of the SkySQL™ Cloud Data Suitelast September! Here is a snapshot of the latest developments with our Cloud Data Suite, a collection of software components that provides a highly available database solution in a cloud environment, based on MySQL & MariaDB, deployable in the Amazon Cloud, i.e. AWS.

What does a cloud computing expert need to know? How do you hire a cloud computing expert? Competition for operations & DBAs is fierce, so you’ll want to know how to find the best.
If you’re a systems administrator or ops guy, you may want to prepare for an interview for such a position. Meanwhile, if you’re a director of it or operations, a recruiter or manager in HR, you’ll want to have some idea how to find the right candidate.
Here’s my guide to do just that. You may[Read more...]
I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a local machine. Totally sweet.
When we were living at 6162 NE Middle in the nine-eight 292, we got an 80386 which ran Doom. Yeah, the original one, not the fancy new one with the double barrel shotgun, but it would probably run that one, too.[Read more...]
Amazon announced high I/O instances today. This is huge for anyone with a database larger than available memory, as it’s been a complete nightmare dealing with EBS up till now. Now your Cassandra, MongoDB, MySQL, or whatever your using should be able to perform well without requiring keeping your entire dataset in memory.
With each instance you get 2x1TB of disk. In this tutorial I’ll be setting it up as a RAID0 to get a single 2TB disk which should deliver excellent performance.
Before you get started, make sure you’ve got mdadm installed:
apt-get install mdadm
To begin, check fdisk and make sure your 1TB drives are mounted.

My first computer program was written almost quarter a century ago on a BK-0010 computer. It was very simple: the program asked the user to enter their name and then greeted the user using the entered name, like “Hello, Artem!”. I was fascinated. A couple of lines written in Vilnius BASIC transformed a piece of metal and silicon into a considerate thing that cared about a person’s name enough to remember it :-). Of course, the first experience doesn’t represent the day-to-day routine of software development, but the moments when I see a couple of lines making an amazing transformation still enchant me, and remind me why I’ve been writing code all this time.
I’ve just experienced this very same first-time feeling as we’ve released[Read more...]
Topics for this podcast:
*OpenStack, Amazon, Eucalyptus and Citrix engage in open cloud warfare
*Microsoft spins off new company for openness
*Updates on automation players Puppet Labs and Opscode with Chef
*Percona turns attention to MySQL high availability
*Open APIs as the fifth pillar of modern IT openness
We’ve seen the rise of open source software in the enterprise and also beyond the IT industry, but the real keys to openness and its advantages in today’s technology world — where efficient use of cloud computing and supporting services are paramount — exist in open application programming interfaces, or APIs.
Open source software continues to be a critical part of software development, systems administration, IT operations and more, but much of the action in leveraging modern cloud computing and services-based infrastructures centers on APIs. Open APIs are the new open source.

Read the original article at $1000 per hour Servers, Anyone?
Amazon's spot market for computing power is set up as an open market for surplus servers. The price is dynamic and depends on demand. So when demand is low, you can get computing instances for rock bottom prices. When you do that you normally set a range of prices you're willing to pay. If it goes over your top end, your instances get killed and re-provisioned for someone else. Obviously this wouldn't work for all applications, like a website that has to be up all the time, but for computing power, say to run some huge hedge fund analytics, it might fit perfectly.
A recent post on SEO MOZ alerted us to an interesting story where spot instances spiked to[Read more...]
When I spoke at Percona Live (video here) on running an E-commerce database in Amazon EC2, I briefly talked about using RAID 10 for additional performance and fault tolerance when using EBS volumes. At first, this seems counter intuitive. Amazon has a robust infrastructure, EBS volumes run on RAIDed hardware, and are mirrored in multiple availability zones. So, why bother? Today, I was reminded of just how important it is. Please note that all my performance statistics are based on direct experience running a MySQL database on a m2.4xlarge instance and not on some random bonnie or orion benchmark. I have those graphs floating around on my hard drive in glorious 3D and, while interesting, they do not necessarily reflect real-life[Read more...]
In the press in the last two days has been the reported outage of Amazon Web Services Elastic Compute Cloud (EC2) in just one North Virginia data center. This has affected many large website includes FourSquare, Hootsuite, Reddit and Quora. A detailed list can be found at ec2disabled.com.
For these popular websites was this avoidable? Absolutely.
Basic scalability principles if deployed in these systems architecture would have averted the significant downtime regardless of your development stack. While I work primarily in MySQL these principles are not new, nor are they complicated, however they are fundamental concepts in scalability that apply to any technology[Read more...]
Netflix went down over three hours ago, and everyone is on edge here. My son just started reciting the script to "Monty Python and the Holy Grail" in an attempt to keep our courage up. This may be the last thing I ever write, so — Oh, never mind, it's back up again ... Crisis averted, and on to this week's developer news.

Paranoid Android. Canonical and Gnome. A new OSI. And more.
If you are interested in the potential violation of the GPL by the Android kernel you have probably already immersed yourself in the numerous blog posts published on the topic. If not, start with Sean Hogle’s analysis or Bradley M Kuhn’s overview of the original allegations and work backwards from there, not forgetting a detour for the obligatory Microsoft connection. Linus Torvalds said claim “seems totally bogus”. In the
Amazon's EC2 and its sister S3 service have been indisputable leaders in IaaS for a long while now and GlassFish and more generally J2EE/JavaEE took advantage of it starting in 2008 (see here and here), with documented how-to's and significant production references.
Just yesterday, AWS's Evangelist Jeff Barr announced[Read more...]
