Classless Inter-Domain Routing Acronym. CIDR.  Classless Inter-Domain Routing ; normally an IP address notation such as 192.168.1.0/24 indicating a block of addresses. The number after the slash indicates how many bits are in the mask; bits to the right are not masked. CIDR (Classless Inter-Domain Routing or supernetting) CIDR (Classless Inter-Domain Routing, sometimes called  supernetting ) is a way to allow more flexible allocation of Internet Protocol ( IP ) addresses than was possible with the original system of  IP address  classes. As a result, the number of available Internet addresses was greatly increased, which along with widespread use of network address translation ( NAT ), has significantly extended the useful life of IPv4. cidr calculator Follow below link http://www.subnet-calculator.com/cidr.php http://jodies.de/ipcalc?host=192.16.0.1&mask1=16&mask2= CIDR - Classless Inter Domain Routing CIDR - C...

Elastic Load Balancer We launched Elastic Load Balancing (ELB) for AWS  (see  New Features for Amazon EC2: Elastic Load Balancing, Auto Scaling, and Amazon CloudWatch  to see just how far AWS has come since then). Elastic Load Balancing has become a key architectural component for many AWS-powered applications. In conjunction with  Auto Scaling , Elastic Load Balancing greatly simplifies the task of building applications that scale up and down while maintaining high availability. On the Level Per the well-known  OSI model , load balancers generally run at Layer 4 (transport) or Layer 7 (application). A Layer 4 load balancer works at the network protocol level and does not look inside of the actual network packets, remaining unaware of the specifics of HTTP and HTTPS. In other words, it balances the load without necessarily knowing a whole lot about it. A Layer 7 load balancer is more sophisticated and more powerful. It inspects packets, has access t...

AWS Linux instance connect through Putty Download the putty and Puttygen for free from site open the puttygen go to conversion tab and import the pem file then save as a private key then save without passphrase private key Once private key save and load in putty for authentication Open the putty and enter the IP address and add the Auth Browse and load the private key and save the session for future for further session always open the save session to connect the Linux instance                                                          Thank You

Edge computing Edge Computing as “pushing the frontier of computing  applications, data, and services away from centralized nodes to the logical extremes of a network. It enables analytics and data gathering to occur at the source of the data. Edge computing  pushes  applications , data and  computing  power (services) away from centralized points to the logical extremes of a network. ... The target end-user is any Internet client making use of commercial Internet  application  services. What is Edge Computing?  'edge' refers to the computing infrastructure that exists close to the sources of data, for example, industrial machines (e.g. wind turbine, magnetic resonance (MR) scanner, undersea blowout preventers), industrial controllers such as SCADA systems, and time series databases aggregating data from a variety of equipment and sensors. These devices typically reside away from the centralize computing available in the cloud....
