When a portion of Amazon’s Elastic Cloud Computing (EC2) was unreachable in the early AM of April 21, 2011, so were some websites and services that are hosted on Amazon’s EC2 environment. It triggered a wave of news across the Internet and people were quick to question the reliability of cloud-services and what it could mean for the future of the cloud-service industry and the many solution providers and services that rely on them.
Taulia runs on Amazon’s EC2 because we are convinced of the benefits of a distributed computing setup and continue to build for the cloud to fully leverage its benefits and opportunities. So are other large organizations with high availability requirements, such as SAP and Netflix, who also successfully run their services on Amazon EC2. Even SAP certified their solutions to work with Amazon’s cloud offering.
While many large companies continue to trust in Amazon’s offering, we also know it is very important for our customers to understand what the Amazon outage meant for Taulia and whether our platform was affected by it.
Was our platform affected?
Was our platform not affected by the outage because of luck?
No. Our platform wasn’t affected by the outage by design.
Taulia’s cloud-based technology platform has been designed and setup to run across multiple servers that are distributed across multiple regions (Amazon operation areas that are physically very far apart) and multiple data centers (availability zones in Amazon speak). Taulia is operating in the US east and US west region and within multiple zones there. Amazon’s website has more details about availability zones and regions.
This means, in the event that not only one server, but an entire Amazon data centers goes down, the Taulia platform continues to seamlessly operate without interruption from another zone or region. Amazon commits to 99.95% availability for each such region as per our Amazon EC2 Service Level Agreement and operating in multiple regions adds to the reliability and availability of our infrastructure.
In addition to our redundant infrastructure, Taulia maintains stringent data backup procedures in full compliance with Amazon’s high-availability scenarios and recommendations. Of course, this also includes 24/7 real-time monitoring of all our systems and services, an on-call operations team and automated diagnostics and recovery scenarios.
Last but not least, Taulia has received the Taulia Completes SAS 70 Type II Certification, which is issued by the American Institute of Certified Public Accountants (AICPA). This includes rigorous testing and an extensive audit process that takes months of preparation. It certifies the reliability and availability of our service, including proper safeguards to protect the security, privacy and sensitivity of all customer data.
With our high availability infrastructure in place, we are happy that our customers continue to trust in our offering and are glad to expand into new physical locations in the near future to support our system growth and to comply with government regulations outside of the US and enterprise clients with a need for local availability and even faster access to the Taulia solution.
