“If it ain’t broke don’t fix it.”
It’s a common sense advice, and many IT managers use this to explain why their infrastructure isn’t virtualized yet. Server virtualization technologies have been around for more than a decade now, but some businesses prefer the proven reliability of good ol’ dedicated servers. (more…)
We live in a world where internet users cannot tolerate even a few minutes of downtime. When Google or Twitter gets inaccessible even for a few seconds, it creates a havoc in the online world.
The reason why many web hosts now move to cloud solutions is to ensure high availability and minimal down time for their hosting. In our role as Outsourced hosting specialists for web hosts, we help setup and maintain suitable high availability solutions for them.
In an ideal world, where nothing ever goes wrong, high availability is a topic that never matters. But sadly, the real world scenario is way too different from this ideal situation.
Service failures and machine crashes can happen in the most unexpected times. Such catastrophic events may often lead to business downtime and customer loss. (more…)
MySQL is by far the most popular database used for web applications. It is a very easy database to use, but it doesn’t have the best uptime record. Many database issues such as corrupted tables, resource limits, or replication errors often lead to website downtime. (more…)
$700 for a 64 GB iPhone 6s? Seemed too good to be true, but that’s what the mail in my inbox said. It didn’t look spammy, so, I clicked on the link, and went to the gadget website. Everything looked legitimate with good user reviews. Great! So, I clicked “buy”, and… the website just went blank. It refused to load any more. I went back a page, but the site was still down.
Virtualization refers to hosting a number of virtual server instances over a single physical machine. Dividing resources such as CPU, RAM, storage and I/O among multiple instances, helps in maximum hardware utilization. Statistics show that every business organization has virtualized over 70% of their servers.
To manage a virtualized environment, businesses need a management solution that enables optimal distribution of server resources among various virtual instances. A virtualization management solution helps to do this without much time or overhead. (more…)
Most of us are familiar with LAMP, the most popular free/open source solution stack in use today. There is an, not as popular, alternative that database intensive site owners might be interested in: LAIP. While LAMP stands for Linux, Apache, MySQL and PHP; LAIP swaps out Oracle’s MySQL server for IBM’s Informix database server.
The term high availability is the buzz word nowadays. Nobody tolerates downtime, whether it is the owner of a web site, owner of a server or owner of a data center. The challenge is how you can offer the least down time and the term “high availbility”, has it all.
DRBD refers to “Distributed Replicated Block Device” and is used for building high availability (HA) clusters. This can be attained by mirroring or replicating a block device via network. DRBD can be considered as equivalent to a RAID 1 setup.
