IBM PowerHA SystemMirror vs. OpenText Availability vs. OpenText Server Backup vs. Python Comparison Chart

OpenText Availability continuously replicates physical, virtual, and cloud systems at the byte level, capturing real-time changes with a Recovery Point Objective of seconds, and maintains duplicated Windows and Linux servers at secondary locations for near-zero downtime. In the event of an outage, it offers automated or on-demand failover with integrated heartbeat monitoring and DNS management, followed by seamless failback when systems are restored. Data is secured with AES 256-bit encryption in flight, while three tiers of compression and bandwidth-throttling options minimize network impact. An extensive API allows integration with other applications, and built-in alerting, reporting, and non-disruptive failover testing ensure administrators can monitor health, troubleshoot, and validate disaster-recovery plans without affecting production workloads. OpenText Availability supports any hypervisor, including VMware ESXi/vSphere and Microsoft Hyper-V, and any major cloud platform.

The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. Whether you're new to programming or an experienced developer, it's easy to learn and use Python. Python can be easy to pick up whether you're a first-time programmer or you're experienced with other languages. The following pages are a useful first step to get on your way to writing programs with Python! The community hosts conferences and meetups to collaborate on code, and much more. Python's documentation will help you along the way, and the mailing lists will keep you in touch. The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python's standard library and the community-contributed modules allow for endless possibilities.
