Explanation

Site reliability engineering (SRE) uses software engineering to automate IT operations tasks - e.g. production system management, change management, incident response, even emergency response - that would otherwise be performed manually by systems administrators (sysadmins). The principle behind SRE is that using software code to automate oversight of large software systems is a more scalable and sustainable strategy than manual intervention - especially as those systems extend or migrate to the cloud. SRE can also reduce or remove much of the natural friction between development teams who want to continually release new or updated software into production, and operations teams who don't want to release any type of update or new software without being absolutely sure it won't cause outages or other operations problems. As a result, while not strictly required for DevOps, SRE aligns closely with DevOps principles and can be play an important role in DevOps success

IBM Cloud Satellite is IBM's distributed cloud offering. It provides consistency in services and the ability to deploy anywhere. It is a platform service that allows users to deploy IBM Cloud services outside IBM Cloud data centers. IBM Cloud Satellite can run in a client data center, another cloud, or in-edge networks (distributed cloud framework that brings enterprise applications closer to a data source). When an IBM Cloud Satellite location is established, it allows the user to run selected IBM Cloud services in that location.

MongoDB is a cross-platform document-oriented database.

IBM Cloud® Activity Tracker records events in compliance with the CADF standard. These events are triggered by user-initiated activities that change the state of a service in the cloud. The solution empowers users to see, manage and analyze cloud actions. IBM Cloud® encrypts all data in transit, and you can encrypt your data at rest with your own keys, and then monitor the events around the lifecycle of the encryption keys with IBM Cloud® Activity Tracker. IBM Cloud® supports multiple encryption options, whether you're looking for a solution that supports the bring your own key (BYOK) or keep your own key (KYOK) functionality. For an in-depth look at the options to secure your data depending on your organization's needs

Application virtualization: Application virtualization runs application software without installing it directly on the user’s OS. This differs from complete desktop virtualization (mentioned above) because only the application runs in a virtual environment—the OS on the end user’s device runs as usual. There are three types of application virtualization:

Local application virtualization: The entire application runs on the endpoint device but runs in a runtime environment instead of on the native hardware.

Application streaming: The application lives on a server which sends small components of the software to run on the end user's device when needed.

Server-based application virtualization : The application runs entirely on a server that sends only its user interface to the client device.

Explanation

Blockchain and AI have a symbiotic relationship with the cloud. Blockchain provides the trusted, decentralized source of truth, AI powers the analytics and decisions made from the collected data, and cloud provides the globally distributed, scalable, and cost-efficient computing resources to support both technologies.

Explanation

A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. You can subdivide a VPC with subnets, where each subnet can reach the public internet through an optional public gateway. You can assign an FIP to any instance to reach it from the internet, or the other way around. This is independent of whether the subnet is attached to a public gateway. Subnets within IBM Cloud VPC offer private connectivity; they can talk to each other over a private link, through the implicit router. Setting up routes isn't necessary.

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.
