UnixTimestamps: While working on a project, the timestamp for the export or batch process was in Unix TimeStamp. Unix Time is based on Epoch Timestamps. To read the UnixTime, I used to use " https://www.epochconverter.com/ " website. We can use it to convert Unix Time to Human Readable Format. Now, we can also access directly from Chrome Extension. Chrome Extension:  https://chrome.google.com/webstore/detail/utime/kpcibgnngaaabebmcabmkocdokepdaki?hl=en Converts Unix Epoch timestamps to human-readable dates (and dates to timestamps) quickly and easily with Utime.

Understanding How AWS is Physically Set Up For the latest on AWS Infrastructure, see: https://aws.amazon.com/about-aws/global-infrastructure/ This tells us about how physically AWS is set up across the globe. In this map, it shows AWS Regions and few upcoming regions. What is AWS Region? Each region is a geographical area that is the collection of availability zones and data centers. The AWS Regions are kept across the world, where data transmission from the physical device would take less time and to provide the best performance to the customers. There are some consumer-based regions and government based regions (GovCloud). What is an Availability Zone? Availability Zone is a geographical physical location that holds an AWS data center. This is where physical hardware is present and any data that is stored in AWS will be located here. Why Multiple Availability Zones? Considering the High Availability and Fault Tolerance, if there is

What is Cloud? Think about like a Computer, which has a storage or processing power  and utilizing it, Which is present somewhere and  can be connected by Internet Connection. In Reality, It is not just one computer.  It’s more like datacenters having server computers that we would be utilizing. Example: Dropbox, iCloud, Amazon Web Services. Why do we use Cloud? Files that we upload to DropBox/iCloud are going to stored on Server Computers,  which is one of the racks in the datacenter. What are the Benefits of using the Cloud? Common Personal Uses:  Storing the data in Cloud, Backups, Sharing across different devices  (Home Computer, Mobile Devices, Work Computer) and access from different devices. Common Enterprise Uses: On-Premises Data Center: Costly, Takes time for Process of ordering, Installation,  Test them up, Install Operating Systems, Softwares and get them all Up and Running. Disadvantages: Money is wasted if the resources and servers are not used. N
