Abstract
Nowadays, the number of services in the Internet grows more and more.
Hardware vendors bring to market more powerful and stable servers. Operative
systems are becoming more robust and flexible offering loads of possibilities.
Nevertheless, service outage might happen if one of these components
crashes.
When critical applications come to concern, it is a must to consider high
availability techniques. By applying them, critical applications would be still
available even in case of hardware, connectivity components or operative
system failure.
On one hand, functional description, component architecture and a comparison
between three software-layer high availability solutions is written.
On the other hand, it is necessary to enable SNMP protocol in every server, as
the platform must be installed in a production environment within mobile
operator's network. Integration with SNMP manager used by the customer
must be achieved. A brief study of the protocol and its components are
explained.
Platform design and implementation have been done in a development
scenario. Beside, the client has another identical scenario to approve software
and platform. This demo scenario has the same configuration than the
development and production scenario. When the system has been approved,
then production scenario must be configured in the same way than
development and demo scenario. To deploy configuration and software
releases, install scripts were implemented and packaged in RPM.
Lastly, a high availability platform running critical services with SNMP
monitoring has been achieved. Moreover, integration within mobile operator's
network has been done successfully. Since October 2007, the system is
offering services running on the high availability platform implementation based
on this project.
