Any application you pick up, there are some issues – big or small. There
will be copy-paste code, mistakes, algorithms which could have better thought
through. But what distinguishes an antipattern from these normal errors is
that like patterns these antipatterns are recurring throughout the code base.
In my recent experience in dealing with performance issues, I had observed
certain recurrent themes that are undermining the overall application
performance. Most of these antipatterns are well documented but it seems we
do not learn from others mistakes. We need to make our own mistakes. I am
recounting some of the common patterns that I observed in the recent months.
Excessive Layering - Most of the underlying performance starts with the
excessive layering antipattern. The application design has grown over the
usage of controllers, commands and facades. In order to d... (more)
Big Data has caught the fancy of each and everyone. Consumer and enterprise
world is looking to adopt the Big Data. Analysts are talking about it,
proclaiming it to the next big thing!
Below is my take on how the Big Data market space will evolve in 2012 and
years to come.
Data Analytics Service – We will start seeing SaaS vendors that will start
offering data analytics as a service (e.g., 1010data). These vendors will be
able to pull in your unstructured data and provide you standardized reports
and data services. This is very similar to the Web analytics (like Omniture)
but ac... (more)
Performance is one word that is used to describe multiple scenarios when
talking about application performance. When someone says I need a High
Performance Application, it might mean any/all of the following:
Low web latency application ( meaning low page loading times) Application
that can serve ever increasing number of users (scalability) Application that
does not go down (either highly available or continuously available)
For each of the above, as an architect you need to dig deeper to find out
what the user is asking for. With the advent of cloud, every CIO is looking
to buil... (more)
Cloud based services are so ubiquitous that it is almost impossible to
imagine our daily life without these. These services range from web e-mail
services like Gmail to productivity apps like Evernote to Social Networks
like Twitter to Information services like Weather.com. I can count at least
twenty different services that I use on a daily basis and probably hard to
live without. I get tremendous value from these services, both personally and
professionally. However, there is an ugly side to these services. Each of
these services live in their own island and it is hard to go on... (more)
Google IO 2012 developer conference has just concluded last week amid lot of
fanfare. I for one think that Google has lot more influence on Enterprise
technology than it seems. Some of what Enterprises see as latest and
greatest of technology (such as Map Reduce) has been pioneered in Google a
while ago. This is one the main reasons why I followed this event closely.
Over the 3 days Google had several technology and product announcements
across the product lines. Here are the top 5 picks at Techspot.
#1 Google Compute Engine
With Compute Engine, Google made it intentions clear ... (more)
