BABOK
1.Planning and Monitoring
2.Eliciatation and collaboration: (Requirement gathering)
3.Requirement life cycle
4.Strategy analysis (future and transition state)
5.Requirement analysis and design definition
6.Solution evaluation

PMBOK
1.Needs Assessment
2.Stakeholder Engagement
3.Elicitation
4.Analysis
5.Traceability and Monitoring
6.Solution evaluation

Menarik, kalau menurut PMI, maka Business Analyst adalah subset dari Project Management. Karena BA fokus pada Product Requirement, sementara PM fokus pada Project Requirement. Dan PM sendiri adalah subset dari EA, karena EA ada pada enterprise wide, diatas project wide.

Capacity Planning: Performance and Forecasting

Metcalfe’s law states that the financial value or influence of a telecommunications network is proportional to the square of the number of connected users of the system (n2). The law is named for Robert Metcalfe and first proposed in 1980, albeit not in terms of users, but rather of “compatible communicating devices” (e.g., fax machines, telephones). It later became associated with users on the Ethernet after a 13 September 1993 Forbes article by George Gilder.

Moore’s law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years. Moore’s law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production.

AWS:
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes.

Wiki:
DevOps is a methodology in the software development and IT industry. Used as a set of practices and tools, DevOps integrates and automates the work of software development and IT operations as a means for improving and shortening the systems development life cycle.

AWS ini definisinya unik juga “philosophies” sementara Wiki lebih normative -methodology

Server Comparison

Apache ActiveMQ vs Apache Kafka vs Redis

Apache ActiveMQ is an open source message broker written in Java together with a full Java Message Service (JMS) client
Apache Kafka is a distributed event store and stream-processing platform.

What’s the Difference Between RabbitMQ and Redis? RabbitMQ is a message broker, while Remote Dictionary Server (Redis) is an in-memory key-value data store. However, you can compare the two technologies, because you can use both to create a publish-subscribe (pub/sub) messaging system

Redis (Remote Dictionary Server) is an open-source in-memory storage, used as a distributed, in-memory key–value database, cache and message broker, with optional durability. Because it holds all data in memory and because of its design, Redis offers low-latency reads and writes, making it particularly suitable for use cases that require a cache. Redis is the most popular NoSQL databas
