Is web-scale networking secure? This infographic breaks it down.
At Cumulus Networks, we take a lot of pride in the fact that web-scale networking using Cumulus Linux can have an immense impact on an organization’s ability to scale, automate and even reduce costs. However, we know that efficiency and growth are not the only things our customers care about.
In fact, many of our customers are interested first and foremost in the security of web-scale networking with Cumulus Linux. Many conclude that a web-scale, open environment can be even more secure than a closed proprietary one. Keep reading to learn more or scroll to the bottom to check out our infographic “The network security debate: Web-scale vs. traditional networking”
Here are some of the ways web-scale networking with Cumulus Linux keeps your data center switches secure:
- Cumulus Linux uses the same standard secure protocols and procedures as a proprietary vendor: For example, Openssh is used by both traditional closed vendors and Cumulus Linux. The standardized MD5 is used for router authentication, and Cumulus supports management VRF.
- Web-scale networking has more “eyes” on the code with community support: Linux has a large community of developers from different backgrounds and interests supporting the integrity of the code. Since an entire community of Continue reading

4.Tuples
A tuple is similar to a list. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas in a list, elements can be changed. A tuple is created by placing all the items (elements) inside a parentheses ()
- We generally use tuple for different datatypes and list for homogeneous similar datatypes.
- Since tuple are immutable, means value can not be changed.
- Tuples that contain immutable elements can be used as key for a dictionary. With list, this is not possible.
- If you have data that doesn’t change, implementing it as tuple will guarantee that it remains write-protected.
Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses)
CODE:
OUTPUT:
5 .Dictionary
Python dictionary is an unordered set of key:value pairs , with the requirement that the keys are unique (within one dictionary). A pair of braces creates an empty dictionary: {}.Dictionary have no concept of order among elements.
Keys are unique within a dictionary while values may not be.The values Continue reading
Lenovo Drives HPC From The Middle Ground
While we all spend a lot of time talking about the massive supercomputers that cultivate new architectures, and precisely for that reason, it is the more modest cluster that makes use of these technologies many years hence that actually cultivates a healthy and vibrant HPC market.
Lenovo picked up a substantial HPC business when it acquired IBM’s System x server division two years ago and also licensed key software, such as the Platform Computing stack and the GPFS file system, to drive its own HPC agenda. The Sino-American system maker has been buoyed by higher volume manufacturing thanks to the …
