Fast and secure: Red Hat's® OpenShift® enables developers to containerize and deploy workloads quickly and securely.

Scalable: Red Hat's® OpenShift® enables developers to scale workloads across multiple data centers and multizone regions. Organizations can then monitor, log, and secure apps.

Remember below severity level 4 = Minimal 3 = Some 2 = Significant 1 = Critical

IBM Cloud® Identity and Access Management (IAM) provides secure access control that enable developers to do all sorts of useful things. For example, if an organization’s corporate security policies require that IBM Cloud credentials always be encrypted and rotated every week, developers can use IAM to securely provide credentials that write to the Cloudant Service.

IAM policy enables a subject to access a resource. There are three primary values in a policy: a subject, roles, and resources.

Continuous delivery lets development teams automate the process that moves software through the software development lifecycle, and it can provide many benefits when provisioning an integrated toolbox, including the following: -Reduce time to deployment through continuous testing and development -Decrease the costs associated with traditional software development -Scale software development based on project size -Deploy code automatically into each phase of the development cycle A continuous delivery tool enables you to use open source tools to build, deploy, and manage your applications. By integrating sets of tools, you can create repeatable and manageable tasks, not only for your development team but also your operations team. Open source continuous delivery tools you can use for a strong continuous delivery pipeline include: Jenkins, Concourse CI, Spinnaker, Travis CI, GoCD and GitLab CI

Explanation

Subnets are the foundational building blocks used to deploy cloud resources in your public cloud VPC. They are bound to a single zone and cannot span multiple zones or regions, which helps with security, reduces latency, and improves availability. Create multiple VPCs and subnets easily by using the suggested prefix ranges and preconfigured network security policies or design and define your own address prefixes and custom security policies. CIDR blocks 161.26/16 and 166.8/14 are both reserved and routed into every subnet. Read about our service endpoints available for IBM Cloud VPC. The default quota limit for the number of subnets that can be created within a VPC is 15.

An IBM Cloud® security group is a set of IP filter rules that define how to handle incoming (ingress) and outgoing (egress) traffic to both the public and private interfaces of a virtual server instance. The rules that you add to a security group are known as security group rules.

Explanation

The DevOps toolchain tools build, deploy, and manage apps that make development and operations repeatable and easier to manage. A continuous delivery service is required before an IBM Cloud Toolchain can be executed. Toolchains are a set of tools that are used to automate the process of building, deploying, and manage applications. You can create toolchains from a variety of sources including other IBM Cloud services, third-party software, and open-source tools.

The IBM Blockchain Platform uses Hyperledger Fabric, so when you use the IBM Blockchain Platform you're experiencing that core open source code that makes Hyperledger Fabric so secure.

The goals of cloud native are to adopt design patterns, paradigms, and techniques that enable loosely coupled systems build around microservice architecture principles.

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.

Serverless computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto scalable so it can handle extremely active traffic periods.

Serverless computing does-not means there are no physical servers utilized, of course there are servers, but we don't have to manage them, in background cloud provider manage (provisioning, scheduling, scaling, patching and more) for us, this gives developers more time to develop and optimize their front-end application code and business logic. And with serverless, customers never pay for idle capacity. They pay only for the resources required to run their applications, and only when those applications are running.

Serverless is a polyglot environment, enabling developers to code in any language or framework - Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on demand in response to workload, it offers significant cost savings for spiky workloads. But it does not offer the same savings for workloads characterized by predictable, steady or long-running processes; in these cases, a traditional server environment might be simpler and more cost-effective.

Serverless Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring.

Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most notably open-source Apache Kafka event streaming platform.

Benefits:

- Pay only for the time for our code will run.

- Developer don't have to take care of servers or infrastructure, it maintains by cloud provider, so

they can focus more on development and business logic.

- API Management & Integrated event sources.

- Serverless scales up and down on demand in response to workload

Explanation

NoSQL databases are non-relational, which eliminates the need for connecting tables. Their built-in sharding and high availability capabilities ease horizontal scaling. If a single database server is not enough to store all your data or handle all the queries, the workload can be divided across two or more servers, allowing companies to scale their data horizontally.

IBM Cloud® offer three support plan - Basic, Advanced, Premium. [Exam Tips] : Usually students get confused between account types and support plan...Please remember both. IBM Cloud® has three main types of accounts : Lite Account, Pay-as-You-Go: and Subscription accounts

Explanation

Virtual Private Cloud used to run an isolated environment within a public cloud. A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. A VPC gives an enterprise the ability to define and control a virtual network that is logically isolated from all other public cloud tenants, creating a private, secure place on the public cloud. - VPC provides security in two ways. At the instance level protection is provided through security groups. At the subnet level, protection is provided by access control lists. Site-to-site virtual private networks (VPN) can be configured. A public gateway is used to enable egress to the internet for all virtual server instances on the attached subnet. - VPC provides flexibility when customers securely connect to on premises or remote infrastructure. VPCs can be created in various regions around the world. Customers can select a private IP address or bring their own IP address for cloud applications. Using Direct Link helps create a dedicated connection between the cloud and on premises resources. This allows an organization to extend its network and provide a consistent connection without using the public internet. - Responsiveness VPC makes it possible to create responsive cloud applications. Instance profiles with elasticity are used when creating applications for workloads, horizontal scaling, performance monitoring, and load balancing services.
