Explanation

Continuous Integration checks that the application is not broken whenever new commits are integrated into the main branch; prevents significant drift, competing changes, and merge conflicts.

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.

Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage. Compared to traditional on-premises IT, and depending on the cloud services you select, cloud computing helps do the following: Lower IT costs: Cloud lets you offload some or most of the costs and effort of purchasing, installing, configuring, and managing your own on-premises infrastructure. Improve agility and time-to-value: With cloud, your organization can start using enterprise applications in minutes, instead of waiting weeks or months for IT to respond to a request, purchase and configure supporting hardware, and install software. Cloud also lets you empower certain users—specifically developers and data scientists—to help themselves to software and support infrastructure. Scale more easily and cost-effectively: Cloud provides elasticity—instead of purchasing excess capacity that sits unused during slow periods, you can scale capacity up and down in response to spikes and dips in traffic. You can also take advantage of your cloud provider’s global network to spread your applications closer to users around the world.

Key value databases are best at storing data that is structured but doesn't require the relational abilities of a relational database. Data are stored as a key value pair where the key is a unique identifier. These databases are used for storing leaderboards and shopping cart data.

Infrastructural path involves migrating apps from to Cloud to take advantage of cloud native technologies. Virtual Machine and Bare metal included in the Infrastructural path to migration.

Explanation

F5 BIG-IP on IBM Cloud for VMware Solutions provides advanced load balancing, traffic management, and application security within your VMware cluster and directly attached to all of your networks.

Microservices are an architectural approach in which a single application is composed of many loosely coupled and independently deployable smaller components, or services. Characteristic of microservices : - Code can be updated more easily - new features or functionality can be added without touching the entire application. - Teams can use different stacks and different programming languages for different components. - Components can be scaled independently of one another, reducing the waste and cost associated with having to scale entire applications because a single feature might be facing too much load.

Identity and access management, or IAM is used to control access to resources.
