Correct Answer: Block storage stores data by breaking it into evenly sized blocks, which is written to disk. The data stored is highly available because each block is stored multiple times across different disks. Block storage is used for computing situations where users require fast, efficient, and reliable data storage Block storage can be deployed on a Virtual Private Cloud (VPC) or classic environments.

Explanation

Microservices architecture is an approach in which a single application is composed of many loosely coupled and independently deployable smaller services. These services typically have their own technology stack, inclusive of the database and data management model; - Microservices communicate with one another over a combination of REST API's, event streaming, and message broker and - Microservices are organized by business capability, with the line separating services often referred to as a bounded context.

Explanation

Virtualization makes it possible to create multiple virtual machines, each with their own operating system (OS) and applications, on a single physical machine. A VM cannot interact directly with a physical computer.

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Application modernization is the process of updating outdated business systems and applications.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.

Kubernetes relies on YAML configuration files to maintain the application state.

etcd is an open source distributed key-value store used to hold and manage the critical information that distributed systems need to keep running. etcd’s performance is heavily dependent upon storage disk speed, so it’s highly recommended to use SSDs in etcd environments. Redis (for REmote DIctionary Server) is an open-source, in-memory, NoSQL key-value store that is used primarily as an application cache or quick-response database. Redis supports multiple data structures, built-in Lua scripting, multiple levels of on-disk persistence, and high availability. Redis is an in-memory data store and can function as a database, cache, or message broker. In-Correct Answers : MongoDB is an open source, non-relational database management system that uses flexible documents to process and store various forms of data. A NoSQL solution, MongoDB provides an elastic data model that enables users to store and query multivariate data types with ease. This not only simplifies database management for developers but also creates a highly scalable environment for applications and services. MongoDB uses documents or collections of documents as its basic unit of data. Formatted as JSON objects, these documents can store various types of data and be distributed across multiple systems. MongoDB offers a few capabilities that make it stand out from other database management systems, including load balancing, ad hoc database queries, and multi-language support. PostgreSQL, commonly pronounced “Post-GRES,” is an open-source database that has a strong reputation for its reliability, flexibility, and support of open technical standards. PostgreSQL provides the ability to restore databases to a specific moment in time because it maintains a write-ahead log that logs every database change. PostgreSQL features built-in support for multiple procedural languages.

Explanation

Public Cloud is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. In a public cloud model, users get access to servers, storage, network, security, and applications as services delivered by cloud service providers over the internet maintain by the cloud provider. Characteristics of a public cloud: A public cloud is a virtualized multi-tenant architecture enabling tenants or users to share computing resources, residing outside their firewalls. Use Case : Now a days, Organizations are using public cloud computing resources to build secondary infrastructures for disaster recovery, data protection, and business continuity. In-Correct Answer : Private Cloud is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community Cloud is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Hybrid Cloud is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

Microservices architecture is an approach in which a single application is composed of many loosely coupled and independently deployable smaller services.

Broad network access : describes access to services over the network using a Web browser and standard interfaces from any location with a variety of devices including desktop, laptop, and tablet computers.

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. Every VPC has a default ACL that allows all inbound and outbound traffic. You can edit the default ACL rules, or create a custom ACL and attach it to your subnets. A subnet can only have one ACL attached to it at any time, but one ACL can be attached to multiple subnets. To make your ACLs effective, create rules that determine how to handle your inbound and outbound network traffic. With inbound rules, you can allow or deny traffic from a source IP range, with specified protocols and ports. With outbound rules, you can allow or deny traffic to a destination IP range, with specified protocols and ports. ACL rules are prioritized and considered in sequence. Higher priority rules are evaluated first and override lower priority rules. Inbound rules are separated from outbound rules. If no rules are specified, then implicit deny is the default behavior.
