                     “HOLOLENS” is a topic which is probably familiar to you all.. A virtual reality headset with transparent lenses for an augmented reality experience..As I am a student of KCMIT I tried a lot to organized an event of hololens in our college premises but due to least number of student I couldn’t do so..

                             So on 13th September, 2016 Tuesday I had my first hololens experience in Prime College.It was really worth it, as I was not the organizer for the Hololens program in Prime college so I was given a time of 4 min..so I decided to divide those precious time in sets of 2 mins each..The first 2 mins I got to experience a tour kinda thing and the other 2 mins was spent playing game..The scene was aesthetic which was perfectly described by a lady in it..And yah not to forget about the game, I had a really fun time playing it.. I felt like those 4 min went by in a swift of a second. All thanks to Bipin dai, Prithika,Suchitra didi and yah MIC nepal..

                               Actually this is my first blog and I know I am kinda late for blogging but believe me there is many more to come……

Mr. Magnus Mårtensson, CEO at Loftysoft, Microsoft Regional Director – Sweden began the session of Microservices with Azure Service Fabric.

In the age of the Cloud, Application development features :

· Scalability

· Availability

He said, “Are you ready to deploy to production ?”.

 

What is Microservice ?

A small, independently versioned, and scalable customer-focused services that communicate with each other over standard protocols with well-defined interfaces.

· Logic + state that is independenly, versioned deployed and scaled

· Remains always logically consistent in the presence of failures.

· You have multiple-replication of your application, if one fails , another will work.

· Hosted inisde a container code + fonfig

· Developed by a small engineering team.

 

Microservices Architecture :

· Set up servers, install different cluster

· Applications communicate with each other through simple APIs.

 

Monolithic Architecture Vs Microservice Architecture

.NET console style app

· ASP.net

· node.js

· Java VMS

· Arbitary. exe

 

What is Microsoft Azure Service Fabric ?

Service fabric is a distributed systems platform that makes it easy to build scalable, reliable, low latency, easyily manage application for cloud.

 

The Microsoft App Platform

Mr. Mårtensson said, “ Don’t worry about the server, you dont care about your server but your application. Microsoft believes that PaaS provides the best foundation for creating running and managing custom applications. ”

 

New ASP.NET CORE :

· Open source

· Cross platform Compatible

· Build Modern Cloud-based Web App using .Net

 

Build of ASP.NET Core

ASP.NET CORE = MVC + Web api + web pages

· One set of concepts - remove duplication

· Web UI and Web APIs

 

Web API Features

· Attributes Routing

· Model binding and validation

· Link generation

· Formatting (JSOBN, xml and content negotiation)

· Metadata generation ex swagger

· CORS (Cross Origin Resource Sharing)

· OWIN (Open Web Interface for .NET) self hosting

· Authorize Access with JWT bearer tokens

Infrastructure services like compute, storage and networking defined the 1st gen of cloud computing adoption....

Many organizations are increasingly turned to platform service PaaS to create a deploy application more quickly.

Yes, Service fabric is battle hardened for over 5 year

Best MVC (Model-View-Controller) Practices – Pasang Tamang

clip_image002

Mr. Pasang Tamang who is a .NET developer & founder at EyeWeb Sys began the session on topic Best MVC Practices.

What is Service Oriented Architecture (SOA) ?

An approach used to create an architecture based upon the use of services. Services (such as RESTful Web services) carry out some small function, such as producing data, validating a customer, or providing simple analytical services.

What are the services in SOA ?

A service is a self-contained unit of software that performs a specific task. It has three different forms.

Interface - defines how a service provider will perform requests from a service consumer

Contract - defines how the service provider and the service consumer should interact

Implementation - is the actual service code itself

Why you should to use SOA ?

· Exposing services ensures clients get data without directly connecting to data source

· Process reusability among different platforms

· Different UI can access for same process and sources

· Tackle heterogeneous technology stack

clip_image003

New Windows Communication Foundation (WCF) ?

It's previously known as "Indigo", is a runtime, and a set of APIs in the .NET Framework for building connected service-oriented application.

Different types of WCF Contracts

· Service Contract

· Data Contract

· Operation Contract

· Message Contract

What are WCF EndPoints ?

An endpoint is what a service exposes, and in WCF terms, is made up of three things.

It’s ABC of WCF EndPoints – The 3 Things

· Address -location by which the endpoint can be reached

· Binding - shaping the message for the implementation of the Contract at the Address

· Contract - shows operations done at the address

Once service have multiple end points and it can be redundant.

Flexibility of Hosting Option in WCF

· Self-hosting your service : A managed .NET application can host the WCF service itself.

· Hosting in Windows services

· Hosting Using Internet Information Services

Then he demonstrated the MVC coding patterns with SOA approach

Software Design Patterns with .Net – Dixanta Bahadur Shrestha

clip_image002[5]

Mr. Dixanta Bahadur Shrestha, Co-Founder at Leapfrog Academy introduced the basics of Object-Oriented Programming.

Mr. Shrestha said, “If you’re taken to a room with Football, Basketball, Volleyball, Tennisball all at same place and asked to pick a ball, which one will you pick at first ? …

Isn’t that, at an instance you’re getting confused. So, What does that mean ? ……

Simple answer is, for now those balls have no presence at all or it only exists virtually.

Same happens when you deal with Object Oriented Programming. “

He talked about the three basics elements of Object Oriented Programming and discussed them in short

Class – Template of Object

Abstract – Virtual Object

Interface - Behaviour of Object

Why You Should Use Design Patterns in .NET ?

When we talk about Design Patterns, there need to be some sort of standardization and efficient solutions to software design and programming problems that are re-usable in your code. Software Architects and developers use them to build HQ robust apps.

Design patterns allow developers to have interaction with software which can be improved over time, making them more HQ with ad-hoc designs.

Basically there are three types of design patterns :

1. Creational Patterns

2. Structural Patterns

3. Behavioral Patterns

Then, he demonstrated usage of design patterns and how it can help you to optimize your coding style which examples.

Ms.Dibya Tara Shakya started her presentation on an art of SQL server performance tuning by mentioning that the way of fitting data has been changed rapidly followed by the space which has been increased rapidly. She then mentioned about the problem that a user faces, some of them are as follows:

  • DBA meets data
  • user want to use the data
  • the data isn't fast enough
  • the user complain of DBA
  • the server is too slow

She further pointed out the options that the users can have to solve them  after the problem is being found:  event logs, SQL error logs, performance monitor, profiler, extended events, DMVs, activity monitor. After knowing the problem and the option to solve it, the user must think on certain things before selecting an options:

  • think about problem
  • for issues affecting all users
  • for issues affecting a subset of users

Key points that a user must think before choosing  an option as said by Ms.Dibya Tara Shakya are as follows:

  • treat the cause, not the symptoms
  • understanding query processing basics
  • identifying query bottlenecks
  • identifying infrastructure bottlenecks
  • special case-tempdo

Migrating On-Premises workload to Microsoft Azure session in Dev/Tech Day V4 2016

Magnus Martensson ,  Microsoft Regional Director (Sweden) , started the session with a brief introduction to Azure and Global Azure Bootcamp. He showed that cloud is in early majority of technological life cycle  and has the immense potentiality to expand .

IMG_3944

He briefed about the services that the azure has to provide , introduced to azure functions, and discussed about the things that matter while building app in cloud which included: 

  • throughput-increase  number of operations ,transactions ,service calls
  • latency- how to reduce the amount of time that we wait for service call
  • density- how to enable us to run efficient software systems on as few resources as possible maintaining high availability and reliability scalability
  • manageability- how to understand the health and performance of your deployed services at scale
  • Availability-how to reduce impact of failures

Moving on in the session , Mr Martensson  described about the difference between IaaS and PaaS and how the crowd is confused about them . He then clarified that IaaS is just the initial or first generation of cloud computing adoption and much more exciting services are provided by PaaS and we should move to it.

 

The session then progressed on with Mr Martensson describing about the interesting and amazing services that the Azure has to provide and how efficiently a company can benefit from it.

And finally to conclude, he urged the mass to upgrade the on-premise workload and IaaS to PaaS.

Dev/Tech Day, IT Pros Session: Integrating Private Cloud with Azure IaaS Services

Speaker: Mr.Magnus Mårtensson
Since, Dev/Tech Day had three different tracks: Azure, Developers and IT Pro. The track that has been discussed here is IT Pro.  After the introduction session, the attendees of IT Pro were welcomed by Mr.Pradip Kandel on the different hall. Soon after the settlement of attendees, Mr.Pradip Kandel welcomed Mr.Magnus Martensson to present his presentation. Mr.Magnus Martensson specializes in Cloud Computing technologies in general and the Microsoft Azure Cloud Platform in particular. He is the first Microsoft Azure Most Valuable Professional in Scandinavia, a Microsoft Azure Insider and a Microsoft Azure Advisor and has also been awarded MVP of the Year in 2012.

IMG_3896

His presentation was about cloud and changes, cloud service, virtual machines, followed by IT resource manager, features of  cloud with IT  and global azure bootcamps. He mentioned that the cloud has crossed the chasm and is widely being used and everyone might or surely will get a relationship with cloud. There is no other way to be going, this is where we are going within the time.He mentioned what is new and what changed is quiet a lot. He discussed the technology adoption life cycle which contains five different phases:

  • innovators
  • early adopters
  • early majority
  • late majority
  • laggards

He explained about the platform services and infrastructure services of the azure. Storage, followed by networking and tons of other things on azure can be done. The traditional way of storing is gone, people way of thinking about storage changed. After discussing about the base line, Mr.Magnus Martensson briefly explained on the following specific topics.

There are three management portals (so far) and can control things in azure platform. ARM( Azure Resource Management) is the service used to provision resources in your Azure subscription discussed in this session. ARM is used by Microsoft. ASM (Azure Service Management) is the best interacting platform to interact with azure. He explained about the two options for command line management of azure:

  • azure PowerShell
  • azure command-line interface (Azure CLI)

Resource group in ARM is a container for multiple resources in which resources exist in one resource group with ability to span regions and services, created inside azure.A resource is something you provision in your Azure subscription and always belongs to a resource group.For example, a SQL Database, Web App, Storage Account, Service Fabric, Redis Cache, Virtual Machine, IoT Hub, and HDInsight are all examples of a resource.ARM areas of focus: deploy, organize and control.

He mentioned a phrase about IaaS and PaaS "Infrastructure services (IaaS) like compute, storage and networking defined the "first generation" of cloud computing adoption..Many organizations are increasingly turning to Platform services (PaaS) to create and deploy applications more quickly.I call this the shift platform infrastructure to innovation, and it's underway today." Bottom line: IaaS is winning.
He then did a demo on azure resource management resource.azure.com, azure.microsoft.com/en-us/documentation/templates,  github.com/Azure/azure-quickstart-templates are some of the places where one  can create templates and  play with the templates that are available. All of the complications were run by Mr.Magnus to make the attendees easy to understand. The overview of Microsoft azure cloud service architecture was given followed by the information about general virtual machine platform that one can start with.

The session then ended with some questions and answer between the speaker and the attendees, followed by distribution of some freebies to the attendees and a token of appreciation  to Mr.Magnus Martensson.

IMG_3907

 

With a considerable amount of tech enthusiasts present in the room , Prabhjot Singh Bakshi, Director Getwings and Microsoft Regional Director (India) , began with the basics  of azure logic app stating  “ Logic app has  to do with automate the excess and use of data with cloud ,without writing a single code”.

He highlighted that there is  an urging need of organization to incorporate the SaaS software (Facebook ,office 365, etc. ) in their solutions and   that’s where logic app will come in the picture, to integrate these beautiful apps . Moving on, he demonstrated a logic app that connects the twitter and email such that a specific hash tag in twitter when used will send a notification to his email with simple drag and drops and without  even a single line of  code used throughout. Cool ,isn’t it?

 

 

 

Now ,with some backdrop to logic app , Mr Bakshi proceeded with details about how logic app  will make the connection of various companies together along with   Bizspark  server .

IMG_3767

Mr Bakshi then demonstrated another logic  app that posts a function with certain message to the twitter . II was quite amazing to experience something that could take a lot of coding  to be completed in a minute or so. Well , that’s how easy logic apps are!

He emphasized that he has never seen such a innovation that can integrate in cloud as IPaaS (Integration Platform as a Service) . He urged the crowd that logic app is a powerful tool and everybody should work with it.

 

Also answering to some of the questions asked, Mr Bakshi  highlighted that logic apps are  much more than what was discussed before and it has a key role in simplifying integration  and making the workflow as automated as possible. It is not only a simple app connecting to other services but it also has the potentiality of growing the enterprises.
