Transition to Cloud Services Advances a CTO’s Career. A Success Story.

25 Feb
By: ClearScale

John’s wireless communications services company was experiencing exponential international growth. And he was worried… As the CTO of the company, his mandates were stressfully ambitious. He had to grow the company backbone infrastructure at triple the rate he has ever done with half the dollars he has spent in the past. His contract with his data center was up for renewal and he needed to absorb the additional cost. His Key Performance Indicators (KPI) for failure rates have been

A “Premier” Stamp of Approval

By: ClearScale

It’s hard to imagine that in just three years since its official launch in the Spring of 2012, the AWS Partner Network (APN) has grown in size to include more than 2200 technology and consulting partners, each specializing in helping companies build successful AWS-based applications and services. Of course, Amazon is well-accustomed to seeing numbers of exponential growth. At this point, there is no denying the fact that Amazon continues to dominate the cloud. And for those of us

Application Development and Operations Under One Roof

27 Oct
By: ClearScale

I have always seen a huge disconnect between development and operations when it comes to building and deploying applications. It’s typical for an application to be built on a single development server and to be handed off to operations to be deployed on a distributed cloud system with numerous servers, load balancers and cloud storage. Operations are then expected to hack things together to make the application run on a distributed cloud system. There is usually no time to

Latest Amazon Outage and Designing for Failure

09 Aug
By: ClearScale

Folks, I am getting really tired of people bashing the cloud by saying things like “Amazon’s outage in third day: debate over cloud computing’s future begins”. People need to understand that the cloud is not some magical place you put your applications into and never have to worry ever again. There are always a bunch of servers in racks somewhere or some power lines going to the data center, and there is always a driver that can run

Amazon RDS is pretty cool!

05 Jul
By: ClearScale

I was playing around with Amazon RDS today. It’s a web service that makes it easy to set up, operate, and scale a relational database in the cloud. In other words, Amazon manages MySQL on the server level and you can connect to it via your application or a MySQL command line. You are also able to perform various database administration tasks via an Amazon API or using something like a RightScale management platform. Here are some of the

Amazon CloudFront

05 Jul
By: ClearScale

I have been setting up CloudFront CDN to serve static content for client websites. CloudFront is a CDN service provided by Amazon and is very easy to set up. Most CDN providers like Akamai, Limelight, and Edgecast require you to sign a contract, but CloudFront is pay-as-you-go. In order to use CloudFront, you need to create a “distribution”, which is in basic terms an association of an S3 bucket containing your static files to an Amazon generated domain name like

The Art of Capacity Planning

05 Jul
By: ClearScale

I just got through reading “The Art of Capacity Planning” by John Allspaw. He is one of the guys that designs and maintains systems for Flickr. This is someone who designed geographically dispersed systems and faced real capacity problems at Flickr. Just to give you an idea: Flickr gets 4 billion database queries per day, stores over 500 million images, and has over 20 million users worldwide. All this experience makes for a great book for anyone who wants to

Cloud Application Architectures

05 Jul
By: ClearScale

I just finished reading “Cloud Application Architectures” by George Reese. It’s good reading for folks that are just getting into cloud computing but are already somewhat technically savvy around systems engineering. The book is focused on AWS, as it's the prevalent and most feature-rich public cloud out there. It’s a good primer for folks getting started with AWS and has some cool AWS command line tool examples and goes over some of the AWS services and concepts. The
