Horizontal pod autoscaler enables customers to determine the minimum or the maximum number of pods to run the CPU and memory utilization the pods should utilize. The HPA automatically scales the workload to match the demand. When there is an increased workload, it deploys more pods. When there is a decrease in the workload, it communicates to the workload resource to scale back down.

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

Block storage is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Use Cases: Block storage suitable for low latency workloads where consistently high speeds required. Features: -Offer volume size from 20 GB to 12 TB, -Provide encryption for data at rest -Provide IOPS upto 48,000 IOPS -Highly available and resilient.

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.

Explanation

Cloud Functions lets you focus on writing code and building great solutions, without the hassle of setting up, configuring, or maintaining servers. You only pay for the time your code actually runs*, which means no excess capacity or idle time. Cloud Functions scales to fit your exact demand, from once a day to thousands of parallel requests per second.

You can run code for any type of application or backend service, all with zero administration. Invoke your code directly via a REST API, or in response to IBM Cloud services and third-party events.

Because Cloud Functions is open-source and is built around an open ecosystem of event providers, there is never a need to worry about vendor lock-in.

IBM Cloud® Function is server less it does not mean Physical infrastructure resources like virtual server, network, storage disks are not required for IBM Cloud® Function, because these resources are required and managed by Cloud Provider.

Containers are lightweight and portable executable units (images) of software. They supply portability between different platforms and clouds. Containers are self-contained units that are designed to hold applications as well as all libraries and dependencies that the application requires. Containers can be run on physical computers or in the cloud.

Containers do not have an operating system of their own. Instead, they access the operating system of the device they are running on using a hypervisor. This allows them to be more light-weight, easier to provision, and much smaller than traditional virtual machines.

Virtual machine is a virtual re-presentation of physical computer, you can understand it as a computer inside a computer. Each individual virtual machine behaves exactly as though it were its own computer. It has its own operating system, memory, storage, and compute and is totally unaware of other virtual machines that could be running on the same host.

How do containers differ from a traditional VM?

Traditional virtualization leverages a hypervisor to virtualize physical hardware. Each VM contains:

- A guest operating system (OS)

- A virtual copy of the hardware that the OS requires to run

- An application and its associated libraries and dependencies

- Containers, on the other hand, virtualize the operating system. Each container only contains:

- The application

- Its libraries

- Its dependencies

Explanation

Correct Answer : 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. In-Correct Answers 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. While Redis is an in-memory database store, MongoDB is known as an on-disk document store. Although both solutions are built for different purposes, they are often used together to maximize the speed and efficiency of a NoSQL database. 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. 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. Db2 is a relational database with enterprise-grade performance. It provides multizone support allowing it to be run in a highly-available configuration. Note : Cloudant is also a document database that uses JSON files to store and index documents. Its serverless design allows for easy scaling based on need.

While Gen 1 and Gen 2 have many of the same features and functions, Gen 2 provides these additional benefits: - 5X faster virtual server processing. - Up to 80 Gbps network performance on virtual server profiles. - Block storage is larger in Gen 2.
