Business Wire
OpenSAF™, an open source community with projects focused on high
availability (HA) middleware, today announced the public
availability of Release 4.2 of its HA middleware platform. OpenSAF
Release 4.2 implements all major functions of the Service
Availability™ Forum (SA Forum) Application Interface Specifications
(AIS) and features several enhancements from Release 4.1, which
focus on improved manageability, enhanced availability modeling,
the ability to support root and non-root environments for flexible
system design and increased testability for both OpenSAF developers
and users.
“With Release 4.2, OpenSAF continues to improve the general
usability, performance and scalability of its open source, SA
Forum-based middleware implementation for creating highly available
systems,” said Hans Feldt, co-chair of the OpenSAF technical
leadership council. “This new release addresses HA community
feedback and demonstrates continued progress in the OpenSAF
ecosystem.”
Release 4.2 offers the following technical enhancements:
- Improved manageability through
Information Model Management (IMM) enhancements in the following
areas:
- Multiple appliers simplify distribution
of configuration changes throughout distributed parts of an
application
- Enhancements for administrative
operations that enable additional data to be carried, providing
more information when, for example, an error occurs, or when a
configuration change is rejected
- CCB Augmentation is a new feature
resembling nested transactions. It can be used to abstract and
mediate between a high level system model seen by an operator and
the detailed model of an application
- Enhancements to the Availability
Management Framework (AMF) to provide increased functionality and
flexibility:
- Improved support for modeling of
application dependencies. Failures in one application are
automatically recognized and acted on in related dependent
applications
- Integration with the new IMM
enhancements
- Support for the AMF B.04 API, which
represents the latest iteration of the SA Forum AIS
specification
- OpenSAF processes execute as non-root,
improving system security
- Python language bindings for the SA
Forum AIS services to enable rapid development of test environments
for OpenSAF developers and users
OpenSAF has stayed active in the HA middleware community over
the past year, hosting two successful industry events. The 2011
OpenSAF Conference, which took place in Boston in May and the 2011
European Symposium, held in Stockholm, Sweden in September drew
participation from experts, architects and academics in the open
source, HA middleware community. OpenSAF plans to highlight Release
4.2 features and improvements at upcoming industry events sponsored
by the Linux Foundation.
