- Scaling PHP apps via PHP-FPM clustering | Jamie Alquiza – PHP-FPM is a way to move your busted PHP handling from one place to another. It's essentially a pool of processes ready for PHP interpretation through FastCGI. While Apache will service client connections and static content, PHP requests are pushed into PHP-FPM. PHP-FPM allows the creation of process pools, each pool having it's own spawning model (e.g. static number of processes, dynamic with min/max, etc.) and other configurations (what UID/GID to run as, listening socket, etc.). A typical setup would be to create a PHP-FPM pool per tenant in a shared hosting environment.
- KERMIT – KermIT is an opensource IT management solution. KermIT integrates best of breed opensource components with a Web user interface and dashboard to provide a central management solution for IT systems and applications. It provides a consistent, secure framework and a scalable architecture. It manages Linux, Unix and Windows systems. 'Small picture' KermIT relies in the backend on Puppet and MCollective. The license of the developments is the GPL v.3 for the generic part of the source code.
- Random Start Times For Cron Jobs With Puppet : mycfg.net – Periodic scripts which use a common resource can end up being configured to run at the same time for multiple hosts. The result is that tasks like puppet runs or backups can take longer since they are trying to run all at once instead of being staggered. One way to do this is to give each cron task unique times manually. Another way is to add a random sleep before the task runs. My preferred way is to use the fqdn_rand function in puppet. Here's how it works.

- WordPress › HyperDB « WordPress Plugins – HyperDB is a very advanced database class that replaces a few of the WordPress built-in database functions. The main differences are: * HyperDB can be connect to an arbitrary number of database servers, * HyperDB inspects each query to determine the appropriate database.
- ClusterFoundry Blog Highly-Available and Load-Balanced WordPress Cluster – Part 1 – This article explains on how to setup a load-balanced WordPress cluster in a master-slave configuration. The load balancer(HAProxy) sits in front of 2 or more web server nodes (1 Master and 1 Slave) which has the same contents. HAProxy does not only distribute requests, but also checks the health of the services running on the node. If one of the nodes are down, all requests will be redirected to the remaining nodes.
- Deploying Scalable WordPress – The Official Rackspace Blog – […] The end result is a WordPress site that uses Cloud Load Balancers, Cloud Servers, and Cloud Files to deliver an easily scalable, modular configuration.[…]

- Perdition: Mail Retrieval Proxy – Perdition is a POP3, IMAP4 and managesieve proxy server. It is able to handle both plain-text and SSL/TLS encrypted connections, and redirect users to a real-server based on a database lookup. Perdition supports modular based database access. ODBC, MySQL, PostgreSQL, GDBM, POSIX Regular Expression and NIS modules ship with the distribution. The API for modules is open allowing arbitrary modules to be written to allow access to any data store.
Perdition has many uses. Including, creating large mail systems where an end-user's mailbox may be stored on one of several hosts, integrating different mail systems together, migrating between different email infrastructures, and bridging plain-text and SSL/TLS services. It can also be used as part of a firewall. The use of perditon to scale mail services beyond a single box is discussed in high capacity email.
- DeleGate Home Page (www.delegate.org) – DeleGate is a multi-purpose application level gateway, or a proxy server which runs on multiple platforms (Unix, Windows, MacOS X and OS/2). DeleGate mediates communication of various protocols (HTTP, FTP, NNTP, SMTP, POP, IMAP, LDAP, Telnet, SOCKS, DNS, etc.), applying cache and conversion for mediated data, controlling access from clients and routing toward servers. It translates protocols between clients and servers, applying SSL(TLS) to arbitrary protocols, converting between IPv4 and IPv6, merging several servers into a single server view with aliasing and filtering. Born as a tiny proxy for Gopher in March 1994, it has steadily grown into a general purpose proxy server. Besides being a proxy, DeleGate can be used as a simple origin server for some protocols (HTTP, FTP and NNTP).
