Crystal vs. Cython vs. V Programming Language vs. VMmanager Comparison Chart

Cython is an optimizing static compiler for both the Python programming language and the extended Cython programming language (based on Pyrex). It makes writing C extensions for Python as easy as Python itself. Cython gives you the combined power of Python and C to let you write Python code that calls back and forth from and to C or C++ code natively at any point. Easily tune readable Python code into plain C performance by adding static type declarations, also in Python syntax. Use combined source code level debugging to find bugs in your Python, Cython, and C code. Interact efficiently with large data sets, e.g. using multi-dimensional NumPy arrays. Quickly build your applications within the large, mature, and widely used CPython ecosystem. The Cython language is a superset of the Python language that additionally supports calling C functions and declaring C types on variables and class attributes.

VMmanager is a platform allowing to automate the management of KVM and LXD virtual machines. It provides flexible tools for the control and management of virtual infrastructure. VMmanager is highly stable. Because of microservice software architecture, different parts of the platform do not affect each other. Even when you have hundreds of nodes in different data centers. VMmanager is fast. It can create KVM VM in less than a minute and it takes only a few seconds to create LXD. Many tasks run asynchronously, so even if users will create many VMs at a time VMmanager will handle the load. Also, you can integrate VMmanager with any billing software to provide VPS hosting and/ or IaaS, SaaS services. BILLmanager and WHMCS integrations are in-build. - Sales automatization and integrations with different billing systems - Hight availability and notifications - Network management - User-friendly interface - IaaS and SaaS providing - Ip-fabric
