Case Study – SME Service Provider

Our client wanted to introduce an AWS like elastic multi-tenant IaaS to its managed service customer base in order to complement its existing traditional VMWare vCloud managed service offering.


The Challenge

The client wanted to avoid vendor lock in and thus an Open Source product with wide spread community support and a quick release cycle was mandated. API based access in addition to traditional enterprise features such as high availability and load balancing was also highly desirable. The client wanted its solution to be scalable and robust with the ability to provide its customers with a self-service portal. Lastly, the client wanted to support live migration and shared storage to provide their customers with transparent failover in case of hardware failure. Finally, the client also wanted to deploy a highly scalable object store to give its enterprise customers an offsite archive and backup solution that integrated with a single identity management system.


The Aptira Solution

Aptira chose Dell hardware for the project. Ubuntu 12.10 was used as the base operating system to deploy OpenStack Folsom. Aptira used Ubuntu Preseed and Puppet configuration manager to fully automate the deployment of the software and configuration. Aptira also wrote custom Puppet code to install CEPH on various storage nodes. The components and their hardware configurations were as follows

  • OpenStack Keystone Identity Service
  • OpenStack Swift Object Store
  • OpenStack Glance Image Service
  • OpenStack Nova Compute Service
  • OpenStack Neutron Network Service
  • OpenStack Cinder Block Storage Service
  • CEPH Distributed File System

The following hardware configuration was used to deploy and manage the services:

  • 1 x Admin and puppet node comprising of a single Dell R610 Dual Quad core Xeon E5620, 48GB RAM, Dual 1Gb NICs
  • 40 x Compute nodes comprising Dell R720xd Dual Hex core Xeon E5-2620, 192GB RAM, Dual 10GbE NICs (480 cores, 7.5 Tb RAM)
  • 2 x Swift Proxy and 2 x Glance Image Server comprising Dell R610 Dual Quad core Xeon E5620, 64GB RAM, Dual 10 Gb NICs each
  • 10 x Swift Storage nodes comprising Dell R720xd Dual Hex core Xeon E5-2620, 48 GB RAM, Dual 10 GbE Nics, 12 x 3TB SATA HITACHI Drives (360 TB of Storage)
  • 3 x CEPH Storage nodes comprising Dell R720xd Dual Hex core Xeon E5-2620, 48 GB RAM, Dual 10 GbE Nics, 12 x 3TB SATA HITACHI Drives (108 TB of Storage)
