Amazon Announces RDS General Availability


+Amazon Web Services Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud.
Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle or Microsoft SQL Server database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS.

But RDS it's not just any regular cloud MySQL service. It is being used in large-scale, mission-critical applications such as Samsung SmartTV, Flipboard, Pinterest, AirBNB, NASA JPL and many-many more.

We have been using Amazon RDS in Multi-AZ deployment (db.m1.large) for more than a year for our CMS PaaS, and can say only good about it. The only big downtime that we encountered was year ago, when there was major downtime in one of US-East regions which largely affected for example Netflix. Again, thanks to a cloud, we were able to relocate our databases to a different server in matter of minutes, and downtime was really minimal.

Multi-AZ deployment in RDS is great, and according to sources, the failover should happen in less than a minute now, which greatly improves high availability. Ability to use Read Replicas (and they dont have to be the same size and speed as master, in fact, read-heavy application will greatly benefit from fast Read Replicas, such as Extra Large DB Instance: 15 GB of memory, 8 ECUs (4 virtual cores with 2 ECUs each), 64-bit platform, High I/O Capacity, Provisioned IOPS Optimized: 1000Mbps). You can also promote read-replica to a Master at any point of time, and monitor the replication status directly through the AWS Management Console.

Amazon RDS Provisioned IOPS is a storage option designed to deliver fast, predictable, and consistent I/O performance, and is optimized for I/O-intensive, transactional (OLTP) database workloads. You can provision up to 3TB of storage and 30,000 IOPS per database instance.

Amazon RDS SLA gives you 99.95% availability for Multi-AZ database instances on a monthly basis. This SLA is available for Amazon RDS for MySQL and Oracle, which are currently the database engines with Multi-AZ deployment support. If availability falls below 99.95% for your Multi-AZ database instance (which is a maximum of 22 minutes of unavailability for a Multi-AZ database instance per month), you will be eligible to receive service credits.

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...

MongoDB: Remove an Arbiter From a Replica Set

Image
Removing an arbiter from MongoDB Replica Set can be quite tricky, and official MongoDB documentation does not say it directly how to do it. I assume that you have auth enabled (just like I have), so lets start with connecting to your ReplicaSet "repl" master as an administrator: mongo mongo.domain.com/admin -u admin -p pass You will see the following prompt: repl:PRIMARY> Type in conf=rs.conf() repl:PRIMARY> conf = rs.conf() { "_id" : "repl", "version" : 8, "members" : [ { "_id" : 0, "host" : "mongo.server.com:27017", "priority" : 2 }, { "_id" : 1, "host" : "mongo1.server.com:27017" }, { "_id" : 2, "host" : "arbiter.server.com:27017", "arbiterOnly" : true }, { "_id" : 3, "host" : "mongo2.server.com:27017" } ] } Now lets adjus...

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, ...
