Explanation

Application modernization is the process of updating outdated business systems and applications. There are many ways to modernize your applications, from integrating existing systems with APIs to doing a full rip-and-replace of infrastructure and building an entirely new application architecture. Common goals of application modernization : - Microservices architecture - DevOps - Cloud migration Benefits of Application modernization : Speed of Development: Since the microservices that make up cloud applications are built once and can be reused over and over, they are easier to use and can be deployed quickly once created. Risk Management: Since one microservice can be used by multiple applications, maintaining security and compliance can be monitored from a central location rather than from within multiple applications. Manage Cost: Since microservices are only written once, the cost to develop them is significantly smaller. The cost to maintain them is also lower since they can be maintained from one central location.

Explanation

Private cloud (also known as an internal cloud or corporate cloud) is a cloud computing environment in which all hardware and software resources are dedicated exclusively to, and accessible only by, a single customer. Private cloud combines many of the benefits of cloud computing—including elasticity, scalability, and ease of service delivery—with the access control, security, and resource customization of on-premises infrastructure. Advantages of private cloud include the following: Full control over hardware and software choices. Private cloud customers are free to purchase the hardware and software they prefer, vs. the hardware and software the cloud provider offers. Freedom to customize hardware and software in any way. Private cloud customers can customize servers in any way they want and can customize software as needed with add-ons or through custom development. Greater visibility into security and access control, because all workloads run behind the customers’ own firewall. Fully enforced compliance with regulatory standards. Private cloud customers aren’t forced to rely on the industry and regulatory compliance offered by the cloud service provider.

Benefits of Cloud Adoption: - Scalability - Cost-Effectiveness - Security - Backup and Recovery - Accelerated Adoption A value of cloud adoption is the collaboration it allows between teams across widespread geographical regions, including international locations.

A security group acts as a virtual firewall that controls the traffic for one or more virtual server instances. A security group is a collection of rules that specify whether to allow or deny traffic for an associated instance. You can associate an instance with one or more security groups and edit the security group rules An Access Control List (ACL) can manage (that is, it can allow or deny) inbound and outbound traffic for a subnet. An ACL is stateless, which means that inbound and outbound rules must be specified separately and explicitly. Each ACL consists of rules, based on a source IP, source port, destination IP, destination port, and protocol. Note : Security Groups control traffic at the virtual service instance level and n Access Control List (ACL) control the traffic at subnet level.

Virtualization is a process that allows for more efficient utilization of physical computer hardware and is the foundation of cloud computing. Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer—processors, memory, storage and more—to be divided into multiple virtual computers, commonly called virtual machines (VMs). Each VM runs its own operating system (OS) and behaves like an independent computer, even though it is running on just a portion of the actual underlying computer hardware. Benefit of virtualization: Virtualization brings several benefits to data center operators and service providers: Resource efficiency: Before virtualization, each application server required its own dedicated physical CPU—IT staff would purchase and configure a separate server for each application they wanted to run. (IT preferred one application and one operating system (OS) per computer for reliability reasons.) Invariably, each physical server would be underused. In contrast, server virtualization lets you run several applications—each on its own VM with its own OS—on a single physical computer (typically an x86 server) without sacrificing reliability. This enables maximum utilization of the physical hardware’s computing capacity. Easier management: Replacing physical computers with software-defined VMs makes it easier to use and manage policies written in software. This allows you to create automated IT service management workflows. For example, automated deployment and configuration tools enable administrators to define collections of virtual machines and applications as services, in software templates. This means that they can install those services repeatedly and consistently without cumbersome, time-consuming. and error-prone manual setup. Admins can use virtualization security policies to mandate certain security configurations based on the role of the virtual machine. Policies can even increase resource efficiency by retiring unused virtual machines to save on space and computing power. Minimal downtime: OS and application crashes can cause downtime and disrupt user productivity. Admins can run multiple redundant virtual machines alongside each other and failover between them when problems arise. Running multiple redundant physical servers is more expensive. Faster provisioning: Buying, installing, and configuring hardware for each application is time-consuming. Provided that the hardware is already in place, provisioning virtual machines to run all your applications is significantly faster. You can even automate it using management software and build it into existing workflows. [Exam Tips]: You can expect few questions from Virtualization and benefits of virtualization.

You can use security groups to enact a set of IP filter rules that define how to handle incoming and outgoing traffic to both the public and private interfaces your instance. Use security groups when you order a virtual server. That way, your server is protected when it is first provisioned. Other Scenarios with solutions listed below : 1. Security scenario: Customers want granular control over traffic at an instance level (apart from network-level firewalls). However, at the same time, the costs of a shared hardware firewall can add up quickly if you need to protect multiple servers in different data centers. Solution: You do not incur extra charges for using security groups. You can use security groups for all virtual servers that need protection in any of our global data centers. 2. Security scenario: You want to avoid configuring firewall rules on each server separately. Instead, you want an easily manageable firewall solution that spans servers in different global data centers. Solution: Define N security groups for N different types of servers in your cloud workload. Manage all rules for a security group in one place. Manage the security group associations with the virtual servers.
