Amazon RDS Added Support for Second Generation Standard Instances

Amazon Web Services announced General Availability of second-gen Standard instances (M3) in Amazon RDS, making RDS even better with almost 50% more computing power thanks to new hardware architecture (Intel Xeon E5-2670 CPU) and about 6% lower cost.

In my previous post I wrote how did I upgrade db.m1.large to 1000IOPS which resulted single-digit ms MySQL read latency - that was pretty nice surprise. This time I've decided to take advantage of faster CPU and lower cost offered by db.m3.large instance type. I was pretty aware that m3.large instance type is not EBS optimized (only db.m3.xlarge and above is) and was ready for performance drop, luckily it never happened - charts read the same except CPU load which seems to have dropped ~ 10%. Because I had multi-AZ RDS setup, the failover took ~ 30 seconds and upgrade was completed in 8 minutes. Nice.

My recommendation is to upgrade your db.m1 instance type to db.m3 as soon as you can - not only you will get lower cost, you will benefit from faster CPU and generally newer and more reliable hardware.

Stubbing and Mocking Static Methods with PHPUnit

Image
PHPUnit has ability to stub and mock static methods. Consider the class Foo : <?php class Foo { public static function doSomething() { return static::helper(); } public static function helper() { return 'foo'; } } ?> To test the static helper() function with PHPUnit, you can write you test like that: <?php class FooTest extends PHPUnit_Framework_TestCase { public function testDoSomething() { $class = $this->getMockClass( 'Foo', /* name of class to mock */ array('helper') /* list of methods to mock */ ); $class::staticExpects($this->any()) ->method('helper') ->will($this->returnValue('bar')); $this->assertEquals( 'bar', $class::doSomething() ); } } ?> The new staticExpects() method works similar to the non-static expects

Enable HTTP/2 Support in AWS ELB

Image
This thread  was started more than a year ago, asking for when Amazon Web Services will add support for HTTP/2  into their ELB. In addition to that, people are also asking, how to configure ELB to support multiple SSL certificates. AWS support team has been reluctant on giving out any specific details on when both of these features will be available, citing: I've verified that the ELB team is aware of the interest in ELB supporting HTTP/2. Please keep an eye on What's New from Amazon Web Services: http://aws.amazon.com/new/ for any updates. What is HTTP/2? HTTP/2 is a replacement for how HTTP is expressed “on the wire.” It is not a ground-up rewrite of the protocol; HTTP methods, status codes and semantics are the same, and it should be possible to use the same APIs as HTTP/1.x (possibly with some small additions) to represent the protocol. HTTP/2 protocol is supported by major modern browsers including IE11, Edge 13, Firefox 47, Chrome 52, Safari 9.1, Opera 38, i

How To Attach Your EBS volume to multiple EC2 instances

Image
Are you exhausted from the complexities and the extra cost associated with the EFS? What if you simply need to share the EBS volume between two EC2 instances? Say no more - Amazon Web Services has an answer for you! Starting today, customers running Linux on Amazon Elastic Compute Cloud (EC2) can take advantage of new support for  attaching  Provisioned IOPS ( io1 ) EBS volumes to  multiple EC2 instances , at  no extra charge ! Multi-Attach option in EBS According to AWS, the Multi-Attach capability makes it easier to achieve higher availability for applications that provide write-ordering to maintain storage consistency. Consider the following scenario: you are running a web application behind the load balancer, and the application expects static assets, such as WordPress media uploads, theme or configuration files, shared between the instances. Instead of using EFS, you could create new PIOPS EBS volume with the Multi-Attach option, mount the volume on each s
