For businesses or organizations whose data is particularly sensitive or mission critical, disk fault tolerance and optimized performance aren’t luxury add-ons but absolute must haves. A Redundant Array of Independent Disks (RAID) provides the additional capacity, reliability and performance they need by combining an array of physical hard disks into a single logical disk.
RAID is a common feature on servers and almost all storage platforms because no single disk could meet all the capacity and performance demands of a busy server. To make RAID an even more valuable feature for customers, LeaseWeb has now automated its implementation – making it much quicker to deploy. Currently the feature is only available for CentOS, Debian and Ubuntu but we are working to bring the feature on board for more operating systems in the near future.
Algolia is a distributed Search-as-a-Service API that processes more than 4 billions user-generated queries per month. Algolia’s DNA is performance, the service is optimized to reply in milliseconds from any location worldwide while maintaining high availability. Today, Algolia’s co-founder and CTO Julien Lemoine provides details on their architecture, showing how they designed their fault tolerant service and how they use LeaseWeb.
Under the hood
Building a highly available API distributed over 12 regions isn’t an easy process – especially since our users can select the set of regions they want to use. Under the hood, we automatically replicate their data and synchronize any change on all their regions. This approach is really different from a CDN that just keeps a cache of recently accessed data, we guarantee our users that any of the regions they have selected have all of the data locally and can serve their search requests. In other words, all write operations of our users are applied on all their regions, even for a very high load of write operations per second.
It’s no secret that LeaseWeb heavily relies on automation to manage the large network of services that we offer. Over the last five years, we have been investing a lot in our internal systems and our strategy has been to have them communicate via APIs (specifically web services).
