Availability is the Foundation
The perfectly available system is right there
whenever your users need it, wherever they are. It responds
consistently and quickly, regardless of time of day or year.
Key Questions
- What is the most appropriate availability goal for your situation?
- How do you know what your current availability is?
- What is driving this availability?
Determine The Goal
There is no end to what you can spend in the
pursuit of availability. Redundant hardware, hot sites,
geo-diverse hosting, full scale application load simulation...
In this sea of
choices, how do you know what activities have a reasonable return on
your investment?
We work with the stakeholders in your
organization to identify and express your availability goals in a
way that everyone understands. This process illuminates what the
impact of availability problems are to the business, customers, and
employees. We also map how this picture varies over the course of
the day, week and year.
Know where you are
How do you know how available you are?
When there's a problem, how do you find out? Most
organizations have great
difficulty knowing enough about how available systems really are and
what is driving that reliability. It's easy to assume that the surface item that caused the last outage is the
most important thing to be addressed because there aren't reliable,
impassionate metrics and other facts to base an analysis on.
We work with you to move beyond reactive
management to a deliberate understanding of how to measure
where you are and why. Sometimes the answer to "What are we
going to do to ensure this doesn't happen again?" is nothing - it
was an expected outcome of deliberate decisions in risk management
that were made transparently in the organization. In an
environment like this, post-outage recriminations instead become
useful after-outage reviews that drive progress forward.
Methodically Improve
Your system is only available when all of the
components (infrastructure, software, and processes) come together.
This means you're only as good as your weakest link.
Investments need to be balanced between each of the areas to ensure
that advances made in one area aren't canceled out by issues in
another.
Preserve Availability over Time
We believe that it isn't enough to solve the
immediate problem in front of you. We work to include in every
project activities to preserve and improve results over time so that
your investment continues to improve in value.
