In an effort to expand the reach of our core high-availability stack, A-Team Systems formally announces three additional layout options for clients to choose from when picking which architecture is right for their sites and applications.

This complete layout offering delivers a great range of balanced options for entry-level systems, while improving high-end clustering capabilities as well. The new list of available layouts is as follows:

  • Replicated Pair: Our entry-level setup consisting of two servers. Web traffic is load-balanced across the two servers if sites work with periodic replication; otherwise, they act as a master/backup pair. Works well for all types of sites. Scaling involves upgrading to a Replicated Cluster or NAS Backed Cluster layout.
  • NAS Backed Pair: A step up from our entry level setup, consisting of two web servers in a load-balanced pair talking to a redundant NAS system. All data is always synchronized across all servers. Good for load-balancing sites that have dynamically user-uploaded content or other files that need to be instantly and consistently available to all web servers. Scaling involves upgrading to a Replicated Cluster or NAS Backed Cluster layout.
  • Replicated Cluster: Fully scalable load-balanced clustering with private LAN, VPN, and dedicated monitoring server. Web servers replicate files at 30-minute intervals or when instructed to do so (i.e. when a site is deployed or modified). Good for sites that have all dynamic content inside the database and do not rely on immediate availability of user-uploaded files.
  • NAS Backed Cluster: Fully scalable load-balanced clustering with private LAN, VPN, and dedicated monitoring server. Web servers talk to a redundant NAS system and all data is always synchronized across all servers. Good for sites that have dynamically user-uploaded content or other files that need to be instantly and consistently available to all web servers.
