IOT for Cisco kinetics IOT Platform

October 31, 2018

Recently, I have been working on few POC related to IOT for Cisco kinetics IOT Platform for motion detection with Axis IP Cameras.

Here is Glossary:

What Kinetic Internet of Things (IoT)?

Cisco Kinetic makes it easy to connect distributed devices (“things”) to the network, and then extract, normalize, and securely move data from those devices to distributed applications. The Kinetic platform also plays a vital role in enforcing policies defined by data owners, so they can control which data goes where, and when.

Cisco Kinetic is a distributed system of software that streamlines your IoT operations by performing the following three key functions:

  • Extract datafrom disparate sources (“things”), regardless of protocol. The data is transformed so it is by the applications that provide business value.
  • Compute dataanywhere from the edge to a destination to provide processing where it’s needed. This enables fast decisions at the point of action, dramatically reduces latency, and makes the most efficient use of network resources.
  • Move dataprogrammatically to get the right data to the right applications at the right time. The platform distributes data in multi-cloud, multi-party, and multi-location situations. Data policies are used to enforce data ownership, privacy, and security.

What is IoT Hub?

IoT Hub is a managed service, hosted in the cloud, that acts as a central message hub for bi-directional communication between your IoT application and the devices it manages. You can use Azure IoT Hub to build IoT solutions with reliable and secure communications between millions of IoT devices and a cloud-hosted solution backend. You can connect virtually any device to IoT Hub.

IoT Hub supports communications both from the device to the cloud and from the cloud to the device. IoT Hub supports multiple messaging patterns such as device-to-cloud telemetry, file upload from devices, and request-reply methods to control your devices from the cloud. IoT Hub monitoring helps you maintain the health of your solution by tracking events such as device creation, device failures, and device connections.

Edge computing—also known as just “edge”—brings processing close to the data source, and it does not need to be sent to a remote cloud or other centralized systems for processing. By eliminating the distance and time it takes to send data to centralized sources, we can improve the speed and performance of data transport, as well as devices and applications on the edge.

Fog computing is a standard that defines how edge computing should work, and it facilitates the operation of compute, storage and networking services between end devices and cloud computing data centers. Additionally, many use fog as a jumping-off point for edge computing.

SharePoint Farm-3 tier of architecture-Web Front End Server-High Availability, Load Balancing and Scalability

August 31, 2018

SharePoint Farm, have 3 tier of architecture, Web front end Server, Application Server and Database Server.
High Availability in SharePoint is implemented at the 3 levels. In database tier, multiple database server have Always On Availability Group to have HA. In Application Server tier, SharePoint Farm, implement HA internally itself.
For Web Front End Server, following are some of the options.
Options possible:
1. Hardware based Load Balancer like F5 , Citrix Netscaler, KEMP
 Plus Points:
o Sticky session
o Strong support for High Availability
o Excellent support for Load Balancing
o Best support for Scalability
 Negative Points:
o Cost for Hardware

2. Software based load Balancer like nginx and haproxy
 Plus Points:
o Sticky session
o Strong support for High Availability
o Excellent support for Load Balancing
o Best support for Scalability
 Negative Points:
o Cost comparatively less the Hardware solution
3. Windows Feature – Network Load Balancer
 Plus Points:
o Sticky session
o Cost Free – Part of Windows server
 Negative Points:
o Limited support for High Availability
o Limited support for Load Balancing
o Does not have good Scalability
o Does not support Multiple subnet IP based network
4. DNS Based Geographic distribution
Either via DNS policy (Reference: https://docs.microsoft.com/en-us/windows-server/networking/dns/deploy/app-lb )
Or core DNS Round Robin implementation
Not a real solution for HA and Load Balancing.
 Plus Points:
o Cost Free – Part of DNS Server (Windows server)
 Negative Points:
o No support for High Availability
o Limited support for Load Balancing
o Limited Scalability

Best of luck for SharePoint Farm with High Availability, Load Balancing and Scalability.


High availability architecture for SharePoint Farm with SQL Server Always on Availability Group-grant permission to account

July 31, 2018

Case:
Recently, I have been working with High availability architecture for SharePoint Farm with SQL Server Always on Availability Group as shown in below diagram.

Gives following error:
Database Mirroring login attempt by user ‘XXXX\YYYY$.’ failed with error: ‘Connection handshake failed. The login ‘XXXX\YYYY$’ does not have CONNECT permission on the endpoint. State 84.’. [CLIENT: 172.19.5.144]

Solution:
Need to grant permission to account which is failing to connect as per message in Errorlog.

GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO [login_mirroring]
GO

Crystal clear focus provide a depth of knowledge.

April 29, 2018

Software Industry is evolving very fast. A lot of dimensions are there. So it is very important for a software professional to focus. Crystal clear focus provide a depth of knowledge.

My career focus is as:

  • Cloud Productivity/Platform (Office 365/Azure)
    • Collaboration and Content (SharePoint)
    • Project and Portfolio Management (Project Server)
    • Application Development

Cloud_Application_Architecture_Guide_EN_US

Application Architecture Cloud Guide attached is very important to grow knowledge about Azure design.

This guide presents a structured approach for designing cloud applications that are scalable, resilient, and highly available. The guidance in this ebook is intended to help your architectural decisions regardless of your cloud platform, though we will be using Azure so we can share the best practices that we have learned from many years of customer engagements. In the following chapters, we will guide you through a selection of important considerations and resources to help determine the best approach for your cloud application:

  1. Choosing the right architecture style for your application based on the kind of solution you are building.
  2. Choosing the most appropriate compute and data store technologies.
  3. Incorporating the ten high-level design principles to ensure your application is scalable, resilient, and manageable.
  4. Utilizing the five pillars of software quality to build a successful cloud application.
  5. Applying design patterns specific to the problem you are trying to solve.

Thanks to Microsoft and LinkedIn, for sharing the guide with me.
