  • High availability clustering on AWS | Zoran’s Blog – How do we keep legacy applications highly available on AWS? I have already written about this previously and there are many good alternatives with the upcoming Cloudwatch instance recovery the easiest to implement. Yet Cloudwatch instance recovery or autoscaling group with min=1,max=1 still requires failure to be detected (1-2 mins) and new instance to be booted up (2-3 mins). If the application can not tolerate outage of 3-5 minutes then high availability clustering may be a good alternative

  • IOWait. (Sysadmin’s bedtime horror story) – […] hope this helps someone out there. The last 3 days, I have had my server crash on me every 2-3 hours. At first I thought it would be a spike in the traffic, since I couldn’t find any crash reports from Apache, and there was a spike in the traffic at this time. So I increased the resources on the server. It crashed again, every 2-3 hours […] It wasn't my case but… who knows in the future?

  • PeteNetLive – KB0000741 – HP and Cisco – VLANs and Trunks Confusion! – When I first started in IT, I went and did my Cisco CCNA. So I learned that to connect Cisco switches and pass VLAN traffic between them, I needed to create a 'Trunk' to pass the VLAN traffic. Fast forward a few years, and I now work for an HP reseller. Very early on I came to realise that what HP called a 'trunk' was very different from what I had been taught. Below is an article I did a while ago about setting up HP Trunks.
  • OpenNOP – Open Network Optimization Platform – OpenNOP is an open source Linux based network accelerator. It's designed to optimise network traffic over point-to-point, partially-meshed and full-meshed IP networks.
    The goal of OpenNOP is to increase network performance over low speed network connections such as ISDN, DSL, DS1, frame-relay, VPN and other network circuits. To accomplish this we can use a variety of techniques such as compression, deduplication, caching and protocol spoofing.
    The objectives for OpenNOP are:
    Produce a low cost solution to increase network performance, improve the end user experience and deliver this in a easy to use appliance image.
    Provide a single solution for networks on terrestrial, cellular and satellite systems.
    Facilitate an open framework that can be extended by 3rd party modules to improve specific network traffic.

  • Plan your Exchange 2007 Backups based on Server Roles – When Microsoft created Exchange Server 2007, one of the biggest changes that they made was the creation of server roles. The concept of roles existed in Exchange server 2003, it was very limited. In Exchange server 2007, there are five different roles which serve five very specific purposes.

    Because these roles are so different from one another, the tasks that an Exchange Server performs, and the code that is installed is entirely dictated by the role that the server is configured to perform. That being the case, it is necessary to completely reevaluate your backup strategy.
