- Traditional network SLA metrics do not take into account changing IT needs.
- Is your network vendor willing to extend service guarantees to application availability?
There are many ways of looking at network service level agreements (SLAs). For telecom providers and certain clients, they can be a mere commercial agreement whereby network downtime will be compensated. In other cases (for example, when downtime can prove very costly or even disastrous to a business), the enterprise customer will need to pay for extra resiliency in the form of five-nines availability or even 100% availability based on 1+1 back-up and/or a 3G wireless broadband data link. Traditional data WAN SLAs still contain the standard metrics, such as jitter, roundtrip delay, latency, availability and MTTR, and this is a good thing overall for making sure the carrier is accountable for the networks. However, IT managers should also be exploring SLAs all the way to applications running on the desktop. Continue reading “Has the 99.999% Availability SLA Gone the Way of the Dodo?”
