About the webinar:
Service mesh is one of the hottest emerging technologies. Even though it’s a nascent technology, many vendors have already released their implementation. But do you really need a service mesh?
Attend this webinar to learn about the levels of maturity on the journey to modernizing your apps using microservices, and the traffic management approaches best suited to each level. We’ll help you figure out if you really need a service mesh.
This talk was done in Feb 2020. Sergey and I co-presented at CTO Forum on Microservices and Service Mesh (how they relate, requirements, goals, best practices and how DevOps and Agile has had convergence in the set of features for Service Mesh and gateways around observability, feature flags, etc.)

Application Modernisation through Event-Driven Microservices confluent
Microservices have emerged as a widely discussed and adopted way to build modern and scalable applications. They are easier to build, manage and maintain than monoliths due to smaller code bases; they isolate complexity, allowing for smaller, more agile teams to create services, and they are flexible—allowing the use of various platforms, programming languages, and tools since these choices affect only an individual service and a small team at a time.
With microservices gone mainstream a few years ago, many organizations have now adopted them; even though all are paying the price in terms of training, solution complexity and operational costs, few are reaping the promised benefits.
Lower velocity, quality and performance issues, along with an overall lack of visibility are what we hear about most often.
In this session, working from our experience as advisors to software development teams, we’ll walk you through some of the symptoms you might experience, their possible causes and some potential solutions.
JS Fest 2019/Autumn. Anton Cherednikov. Choreographic or orchestral architect...JSFestUA
When we developing a loosely coupled and reusable application, often arises the question: how to arrange to communicate between services or applications? To a large extent, it depends on the nature of the request and the granularity of your applications or services.
We will discuss the two classic microservice integration patterns: service choreography and orchestration.
What is the difference between these two modes of communication? Which one we should use? How to ensure data consistency? How to implement disturbed transactions?
We will discuss these issues, consider an example of implementing orchestration on nodejs, and of course we will not forget about logging, monitoring and alerting.
The introduction covers the following
1. What are Microservices and why should be use this paradigm?
2. 12 factor apps and how Microservices make it easier to create them
3. Characteristics of Microservices

[APIdays Paris 2019] API Management in Service Mesh Using Istio and WSO2 API ...WSO2
Stefano discusses how to augment service mesh functionality with API management capabilities, so you can create an end-to-end solution for your entire business functionality — from microservices, to APIs, to end-user applications.
[WSO2 API Day Dallas 2019] Extending Service Mesh with API ManagementWSO2
In this deck, we discuss how to augment service mesh functionality with API management capabilities, so you can create an end-to-end solution for your entire business functionality — from microservices to APIs, to end-user applications.
Early Draft: Service Mesh allows developers to focus on business logic while the crosscutting network data layer code is handled by the Service Mesh. This is a boon because this code can be tricky to implement and hard to test all of the edge cases. Service Mesh takes this a few steps further than AOP or Servlet Filters or custom language-specific frameworks because it works regardless of the underlying programming language being used which is great for polyglot development shops. Thus standardizing how these layers work, while allowing teams to pick the best tools or languages for the job at hand. Kubernetes and Istio Service Mesh automate best practices for DevSecOps needs like: failover, scale-out, scalability, health checks, circuit breakers, rate limiters, metrics, observability, avoiding cascading failure, disaster recovery, and traffic routing; supporting CI/CD and microservices architecture.
Istio’s ability to automate and maintaining zero trust networks is its most important feature. In the age of high-profile data breaches, security is paramount. Companies want to avoid major brand issues that impact the bottom line and shrink market capitalization in an instant. Istio allows a standard way to do mTLS and auto certificate rotation which helps prevent a breach and limits the blast radius if a breach occurs. Istio also takes the concern of mTLS from microservices deployments and makes it easy to use taking the burden off of application developers.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
1. Way to solve
Microservice
problems with
a Service Mesh
Linkerd 1.x implementation chosen for the purpose of a Demo
Andrii Minchekov
Software Architect
3. Microservice challenges
1. Infrastructure is not reliable and sometimes slow,
partial failures possible
2. Request routing and load balancing is hard under scaling
3. It’s difficult to understand what’s happening in real time.
4. Secure communication between services
5. Dev team requires experience with specific microservice libraries,
technology diversity
6. Ops team need to manage and monitor lots of services, which are
being redeployed regularly.
4. Why Service Mesh (Linkerd)?
Stakeholder Concerns Benefits
Management Why do we need it?
What is the cost?
What are the risks? Is it mature
technology?
What dependencies are we introducing
to our business?
● We have fewer outages
● Our services are resilient
● We receive unified visibility
across all services
● Business services are not
touched at all
● We receive much faster pace of
development
● Cost: ~ 2 month to be integrated
against 10 months by integrating
dedicated libs into business apps
1 node needs up to 200mb of
memory, can serve 10k req/sec
● Only 2 years on the market but
based on mature RPC
framework from Twitter (Finagle).
Member of CNCF
● We introduce 1 more technical
service (possibly multiple nodes)
what is the good design principle
to solve complex problems by
introducing layer of indirection
5. Stakeholder Concerns Benefits
Developers
Operations
What do I have to change?
Do I have to learn a new technology?
How to test it?
Is it reliable?
Will it introduce complexity?
Is it secure?
● Get rid of the complex
communication logic from your
code
● Yes, but it’s only declarative
YAML configuration mostly done
by Senior Engineers or even
Operations team
● System tests should be in place.
It’s just 1 more technical service
to dev infrastructure but allows
easily run parallel versions of a
service, do dynamic routing
per-request
● All service communication metrics
will be at your hand with possible
alerting in case of a problem
No cascading failures, they will
be isolated
● Just 1 more service to deploy and
configure but it allows to do easily
staging, blue/green, canary
deployment
● Yes, consistent TLS across all
services supported
6. Service Mesh Overview
It’s a dedicated infrastructure layer to manage service to service
communication in a fast and resilient manner for microservices. It abstracts
the mechanics of reliably delivering requests between services.
Service Mesh is typically implemented as an array of lightweight network
proxies that are deployed alongside app code, without the app needing to be
aware.
8. PROS CONS
● It provides Service Metrics such as success rates,
request volumes, latencies, etc without requiring
changes to application code.
● Easy and quick to adopt Load Balancing, Circuit
Breaker, Timeouts/Retries, Dynamic Routing,
Distributed Tracing, Security for an
existing/legacy applications. Good coordinating
of retries and timeouts across multiple services.
Some Estimates just to implement Discovery
client:
Linkerd setup: ~ 10 days
Add lib per srv: 1 day * 60 services ~ 60 days
● Service developers can focus more on the
business logic while most of service-to-service
communication related functionality is offloaded
to Service Mesh.
● Possibility to easily do Staging, Blue/Green,
Canary, Continuous Deployment, A/B testing
without needing to restart
● Immature
● Only Internal traffic can be handled. No single
entry point is exposed to external clients.
● Resource intensive that increase the number of
runtime instances that you have in a given
microservice implementation.
Up to 200mb of memory required to operate for
1 node, 10k req/sec per node
● Extra hops will be added. Each service call has
to go through an extra hops, xx ms (through
Service Mesh sidecar proxy)
10. Demo time
1. Demo project architecture.
Docker-compose configuration.
2. Linkerd Integration.
Business services are free of code changes.
Only Proxy address as a System property should be provided to service
deployment.
3. Linkerd configuration.
Basic concepts.
Load balancing, Circuit Breaker, Timeouts/Retry, Observability,
Dynamic Routing
15. Dynamic request routing and traffic shifting
Use HTTP header “l5d-dtab” as a dtab rule to be used for routing a particular request
Use namerd service to enable the ability to make dtab changes at runtime, without
needing to restart Linkerd.
