What is Site Reliability Engineering? Site Reliability Engineering, or SRE, is a set of principles and practices that applies software engineering techniques to the challenges of IT operations. SRE originated at Google when engineers needed a more systematic, software-oriented approach to manage and optimize their massive infrastructure. SRE’s main goal
No computer is an island. We connect to so many different servers throughout the day that we don’t even think about it. Until we can’t connect. Or the connection lags so much that you start to consider going offline for a while (gasp!). Maybe you could use a break, but
The age of IPv6 is Upon Us ARIN, the American Registry for Internet Numbers is the authority in charge of distributing IP addresses in North America. ARIN received the IPv4 blocks for North America from the IANA (Internet Assigned Numbers Authority, which is responsible for distribution of IP addresses and
Voice Connectivity is Critical. Your phone systems have gone down and you are unable to communicate with your customers. After several hours of troubleshooting you have managed to get the services up again but what do you do now? Whether you utilize a SIP based VoIP system, digital voice over T1 lines or POTS (plain old telephone service), those voice services need to be available.
We break down the importance of DNS resolution, why resolution time is important, and how website and network monitoring can improve your DNS resolution time.
With the advent of video streaming comes a rise in performance problems, including pixilation, buffering, and latency. Therefore, the importance of keeping the stream flowing has never been more crucial; every second of delayed video load time increases the likelihood that your target market will go elsewhere for the content.
Monitoring Content Delivery Networks enables webmasters to regain control of delivery and deployment of CDN content. Monitoring tools that reach into element-level performance of web pages, such as BrowserView Monitoring at Dotcom-Monitor, enable webmasters to quantify returns and increase efficiency of Content Delivery Networks.
The switch to IPv6 is jumping to light speed. On June 8, 2011 several large organizations, including Google, Yahoo, and Facebook will run a comprehensive test for switching to IPv6. If all goes well most companies will start making the switch. However, the advent of IPV6 is not without problems and the performance monitoring solutions that worked for IPv4, will not work with IPv6.
Using an active external performance monitoring service will be critical with the advent of IPv6. Network and website managers must have a true view into end-user connectivity and the ability to receive instant notification whenever a problem occurs.
