2020-01-15 Wednesday - Istio moving away from a microservices architecture?

An interesting recent blog posting by Chrisian Posta: (co-author of the O'Reilly book: Introducing Istio Service Mesh for Microservices)
  • "Istio is used to help solve difficult application-networking challenges introduced by a microservices/cloud architecture, so why would Istio itself move away from a microservices architecture?"
  • "The most straight-forward answer is: The complexity of the microservices approach proved to not deliver the value or goals it intended. On the contrary, it worked against those goals."

2020-01-11 Saturday - Enterprise Data Lake Resources

This blog posting is a placeholder for interesting resources related to Enterprise Data Lakes:

Background Reading:
    • "Coined by James Dixon, CTO of Pentaho, the term “data lake” refers to the ad hoc nature of data in a data lake, as opposed to the clean and processed data stored in traditional data warehouse systems."
Suggested Amazon Books:

Additional Suggested Reading:

Amazon AWS Data Lakes:

Microsoft - Azure:

Microsoft - SQL Server 2019:
  IBM Data Lake:

Apache Projects:

    • "Flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data. It has a simple and flexible architecture based on streaming data flows. It is robust and fault tolerant with tunable reliability mechanisms and many failover and recovery mechanisms. It uses a simple extensible data model that allows for online analytic application."

Other Open Source Projects:

    • "Presto is an open source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes."
      •  "Presto (or PrestoDB) is an open source, distributed SQL query engine, designed from the ground up for fast analytic queries against data of any size. It supports both non-relational sources, such as the Hadoop Distributed File System (HDFS), Amazon S3, Cassandra, MongoDB, and HBase, and relational data sources such as MySQL, PostgreSQL, Amazon Redshift, Microsoft SQL Server, and Teradata."
      • "Presto can query data where it is stored, without needing to move data into a separate analytics system. Query execution runs in parallel over a pure memory-based architecture, with most results returning in seconds. You’ll find it used by many well-known companies like Facebook, Airbnb, Netflix, Atlassian, and Nasdaq."

2020-01-05 Sunday - Book Review: The Data-Centric Revolution, by Dave McComb

My review for Dave McComb's book (also posted on Amazon)

Why You Should Read This Book
This book will make you feel uncomfortable.
It will challenge your assumptions.
It will stretch you thinking.

If you were not previously familiar with the concepts of Semantic Technology - and the principles of Data-Centric architecture - reading this book will forever divide your professional career into two epochs: Before - and After - having read this book.

The change envisioned by Dave - and outlined in his book is not an incremental shift in thinking - it is a sea change.

The benefits to be achieved are game changers for the business stakeholders - and will upend many in IT leadership roles that prefer the staid status quo. But, for organizations that face life-or-death challenges of remaining competitive, buried under mountains of technical debt, onerous mountains of legacy integration burdens that prevent dynamic and agile responses to changing business demands/threats/opportunities - Dave's vision provides a way to move forward - and beyond.
