The document discusses various cloud design patterns and principles including CQRS, strangler, pipes and filters, circuit breaker, compensating transactions, static content hosting, gatekeeper, event sourcing, sharding, sidecar, and anti-patterns like busy database, no caching, and chatty I/O. It provides descriptions and examples of when to use each pattern to improve scalability, availability, and resilience of applications in the cloud.
In the presentation, we talk about 7 design patterns and 5 antipatterns. It also talks about why you should use design patterns for better architecture. Principle based desing is also discussed. To see the video, visit https://youtu.be/h-_Ns6nmWKw
The Windows Azure Platform (MSDN Events Series)Dave Bost
This presentation was delivered as part of the MSDN Events series of technical seminars and provides a deep dive into cloud computing and the Windows Azure Platform. It starts with a developer-focused overview of the Windows Azure Platform and the cloud computing services that can be used either together or independently to build highly scalable applications. From there, the discussion explores data storage, SQL Azure, and the basics of deployment with Windows Azure.

The 36th Chamber of Shaolin - Improve Your Microservices Kung Fu in 36 Easy S...Stefan Richter
We all know, that software development can not be learned by following checklists and that writing distributed systems is not easy. But wouldn't it be nice, if you had a checklist of the most important things to keep in mind when you start building your own microservices project?
This is what my talk is about. I presented it at codetalks 2016 in Hamburg, Germany. (YouTube video of the talk will follow soon).
No technical details about how to use Kafka or which cloud manager is the best. Just some general principles that will help you to focus on the right things from the beginning. You don't have to agree on all principles, but I am pretty sure that if you just focus on 80% you will be better off. Feedback and comments are very welcome so this list can grow (and maybe even shrink) based on new project experiences.

DevOps in Practice: When does "Practice" Become "Doing"?Michael Elder
DevOps has emerged as the hot trend in development buzzword-ology. With a few quick paragraphs, it proposes to decimate all of the traditional problems you've encountered during your development experience.
In IBM UrbanCode, we build products to help customers follow good DevOps practices. You may think DevOps is about the release process, but really it's about applying a mix of automation and operational practices earlier in your development life cycle so that rolling out to production becomes easier. DevOps promotes a focus on small-batch changes over large complex updates which are harder to predict and harder to roll back when problems occur. With greater velocity, rolling out smaller changes becomes more common place. Additionally, IBM UrbanCode makes extensive application of cloud technology that intercepts well with practices in DevOps around production-like environments.
In this talk, Michael Elder describes how we practice DevOps internally with a mixture of IBM-built and open source tools. He'll discuss the areas that we do well and the challenges that we have with changing our culture around areas like test automation. On top of that, he'll describe how you can leverage these approaches in your own development process!

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

Exploring Innovations in Data Repository Solutions - Insights from the U.S. G...Globus
The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.

Pipes and Filters pattern
Decompose a task that performs complex processing into a series

Event Sourcing Pattern
https://blogs.karthikeyanvk.in
Instead of storing just the current state of the data in a domain,
use an append-only store to record the full series of actions
taken on that data.
The events are persisted in an event store that acts as the system
of record (the authoritative data source) about the current state
of the data.

Sidecar Pattern
https://blogs.karthikeyanvk.in
Deploy components of an application into a separate process or

Applications and services often require related functionality, such
as monitoring, logging, configuration, and networking services

Why Anti-Patterns ?
Application behaves well during all types of testing. But behaves
badly in production.
The development team is then faced with two questions:
• Why didn't this behaviour show up during testing?
• How do we fix it?
https://blogs.karthikeyanvk.in

What is Anti-Patterns ?
Anti-Pattern is a common practice that is likely to cause problems
when an application is under pressure.
It's very difficult in a test environment to simulate real users.

Busy Database Anti-Pattern
Offloading processing to a database server can cause it to spend
a significant proportion of time running code.
Remember stored procedures and triggers !
https://blogs.karthikeyanvk.in
42. Enter Text
No Caching Anti-Pattern
Repeatedly fetching the same information from a resource that is
expensive to access, in terms of I/O overhead.
Also think about stale data
Remember the expiring cache. Absolute or Sliding expiration.
Monitor your application and queries
https://blogs.karthikeyanvk.in
43. Enter Text
Chatty I/O Anti-Pattern
The cumulative effect of a large number of I/O requests can have
a significant impact on performance and responsiveness.
Packaging the data into larger, fewer requests
Problem seen in improper domain division in Microservices.
https://blogs.karthikeyanvk.in
44. Enter Text
Improper Instantiation Anti-Pattern
It can hurt performance to continually create new instances of an
object that is meant to be created once and then shared.
Think about singleton pattern.
Always reuse System.Net.Http.HttpClient or any connection
related broker classes
