  Public Cloud A public cloud is a type of computing in which a service provider makes resources available to the public via the internet. The whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service. The location remains, thus, separate from the customer and he has no physical control over the infrastructure.Resources vary by provider but may include storage capabilities, applications or virtual machines. Public cloud allows for scalability and resource sharing that would not otherwise be possible for a single organization to achieve. Eg: Amazon Web Services, Microsoft Azure, Google Cloud Platform Best AWS Training Institute in Gurgaon Private Cloud  Private cloud is a type of cloud environment where the cloud software is managed by internal IT. Private Cloud provides the same benefits of Public Cloud, but uses dedicated, private hardware. Private cloud means using a cloud infrastructure (network) solely by one c...

Security Groups   When we launch an instance in a VPC, you must specify a security group that's created for that VPC. After you launch an instance, you can change its security groups. Security groups are associated with network interfaces. Changing an instance's security groups changes the security groups associated with the primary network interface (eth0). Best AWS Training Institute in Gurgaon A security group acts as a virtual firewall for your EC2 instances to control incoming and outgoing traffic. Inbound rules control the incoming traffic to your instance, and outbound rules control the outgoing traffic from your instance. When we launch an instance, we can specify one or more security groups. If we don't specify a security group, Amazon EC2 uses the default security group. You can add rules to each security group that allow traffic to or from its associated instances. You can modify the rules for a security group at any time. New and modified rules are autom...

Cloud Computing From traditions we are working with the physical machines and Virtual machines, as an Administrator or a Developer we will be facing plenty of issues like hardware failure, security issues and a lot more. Cloud is the best solution for all the points.  Cloud computing is a model for enabling on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.   Best AWS Training Institute in Gurgaon...
