The Inevitable Cloud Outage: 5 Key Essentials to Safe Guard Your Application

The Inevitable Cloud Outage: 5 Key Essentials to Safe Guard Your Application

By Ofir Nachmani on June 4, 2013

A while back, I was starting up an EC2 instance on the AWS cloud when it entered an endless restart loop.

Disaster Recovery for Amazon EC2 in a Single Click

Disaster Recovery for Amazon EC2 in a Single Click

By Ofir Nachmani on April 18, 2013

In my journey through the cloud I often come across great new initiatives. The interesting fact is that although the cloud is a pure revolution terms such as SLA, TCO and ROI remain valid, new methodologies and techniques are presented to support them in the cloud.

Can We Take Availability Off Cloud Concerns List?

Can We Take Availability Off Cloud Concerns List?

By Krishnan Subramanian on January 15, 2011

One of the concerns cited by people who believe in traditional ways of computing is the issue of service availability in the public clouds. For reasons known only to psychiatrists, they associate availability to the presence of the software inside their organizational boundaries. If we talk to enterprise users who use email system hosted on-premise, […]

Over the past few days I have been having some issues with my Twitter account.  Beyond the well known pauses in the service, outages, etc there are some less known but more annoying problems with twitter search.  It turns out that many accounts don’t show up in search at all.  Therefore, if you are one […]

The Evolution Of Reliability and High Availability

The Evolution Of Reliability and High Availability

By Guest Authors on August 19, 2009

Over the last few decades, the technologies we used and the approaches we took to make our systems reliable have undergone a steady evolution. In some cases the technology has just gotten more reliable through quality control at the hardware level (consider an Intel Blade today compared to my 1986 Zenith 8088 that I wrote […]

High Availability Series: Series Outline

By Guest Authors on August 18, 2009

With all of the talk about reliability, or lack thereof, of SaaS and Cloud based applications, I thought I would write a series on designing applications to be Resilient and Highly Available.  The series sort of started with this post “It’s Inadequate Design That Lets Systems Fail, Not Whether They Are SaaS or Deployed in […]

It’s Inadequate Design That Lets Systems Fail, Not Whether They Are SaaS or Deployed in The Cloud

By Guest Authors on August 18, 2009

There have been many high profile outages lately which have caught peoples attention.  These failures are being used as an argument for why critical systems should remain internal and not be deployed as SaaS or in the Cloud.  Some of these outages included Google App Engine’s performance issues in early July , Rackspace’s loss of […]
