Introduction to IoT

Imagine you wake up in the morning, and your coffee maker has already begun pouring a cup of hot coffee for you. Or you are returning home from work, and you’re just 5 minutes away when your AC automatically starts up so that it’s already cool and cosy when you arrive. So convenient, isn’t it?

How is this possible? Something must be tracking you – whether you are awake or asleep, where you are, etc. In the first case, it is your smartwatch that detects when you are awake and signals your coffee maker to start up. In the second case, your car’s or your mobile’s GPS knows when you are close to home and signals your AC to turn on.

This connected system of devices, like your smartwatch or mobile or AC, is referred to as Internet of Things or IoT…

What is Internet of Things (IoT)

Internet of Things or IoT refers to a network of connected devices that interact and exchange data with each other using sensors or software technologies. Their purpose is to minimize human-to-computer interactions and replace them with computer-to-computer interactions.

IoT devices can vary from smart home devices like smart refrigerators, health monitoring devices, and Alexa to industrial devices like temperature sensors, air quality monitors, and industrial robots.

Why is IoT important

Imagine you are sleeping, it’s 2 o’clock in the night, and you suddenly have a heart attack. Even if you haven’t noticed your hard breathing, the health band on your wrist has already detected a spike in your heart rate. Quickly, it finds the nearest hospital or clinic using GPS and sends them your vitals along with your location. The hospital then dispatches an ambulance to get you, and by the time you arrive, a room is fully prepped with the necessary tools and medications for your treatment.

This is one of the ways IoT systems can save you during critical moments through their fast, automated functioning. Following are some more benefits of IoTs…

IoT systems help save time, improve efficiency and reduce the need for human intervention through automation.
These devices are also accessible from anywhere and at anytime. For example, you can check your security camera while you are out.
Since it is mostly managed using computers and requires less human involvement, it is less prone to errors and inconsistencies.
It is flexible since new devices can be added anytime to expand a system’s functioning.
IoT technology helps develop personalized products for customers, thus helping enhance customer experience.

Working and Components

An IoT system has the following components…

Smart device: Smart devices consist of smart sensors which continuously monitor and collect data from their environment. When it detects specific data (for example, a health band detecting an increase in heart rate the moment you awaken), it either responds to it or passes it to another connected device (like, a coffee maker).
Connectivity: All the devices within an IoT system are connected over the internet through which they share their data with each other.
Graphical user interface: A mobile application or website acts as a graphical user interface which allows users to manage their IoT systems and devices.

Conclusion

The Internet of Things (IoT) is transforming our world by connecting everyday devices to the internet, making our lives more convenient and efficient. From smart homes to connected cars and industrial automation, IoT is revolutionizing how we live and work. As this technology continues to grow, it opens up endless possibilities for innovation and improvement in various fields. However, with these advancements, it’s important to stay mindful of security and privacy concerns. Embracing IoT responsibly will help us make the most of its benefits while safeguarding our personal data and ensuring a better future for everyone.

Azure Cloud Services Overview (Glossary Part 2)

Microsoft Azure Cloud is a set of cloud services taking over the internet to help your company in better management. Many a times people ask what is Azure Cloud in DevOps? Azure offers a bunch of services and tools to help the DevOps team to do their jobs in a better way.

This is the second post in our three part series on Azure cloud terminology. You can check the part one here.

Azure Services Glossary

Azure Functions

Azure Functions are a serverless compute service that allows you to run event-triggered code without managing the infrastructure. It can be built and developed without any additional setup, deploy, and operate in the cloud.
Azure Functions are used to achieve decoupling, high throughput, reusability, and shared.
It’s a separate App service that runs in the App Service Plan. Every function can be invoked using the configured trigger.

Azure Event Grid

Azure Event Grid provides the infrastructure for event-driven computing. The focus here is on events that notify that something has happened. It has built-in support for events coming from Azure services. So it automatically sends messages through Event Grid.
It is used to maximize availability by natively spreading across multiple fault domains in every region.

Azure Service Bus

It is a reliable cloud Messaging-as-a-Service (MaaS). Azure Service Bus will help to decouple the applications from each other, distribute messages to multiple independent back-end systems.
It will also protect your applications from temporary spikes in traffic.
Azure Service Bus Queues allows one-way communication. Whereas Relays provide bi-directional communication.

Azure Storage

Azure storage offers durable storage in the cloud that allows you to store tables, blobs, and message queues.
You can access this storage through HTTP. It is possible to create your own client.
Azure Storage is cost-effective as you will have to pay only for what you need. There is a client library by Azure, but you can also create your client.

Azure Internet of Things (IoT)

It is a cloud service that connects, monitors, and controls billions of IoT assets.
Azure IoT is made up of a circuit board with sensors attached. It will connect to the internet using WiFi.
You can choose from a variety of devices for your solution. IoT devices are pretty different from browsers and mobile apps.

Azure Container Service

It’s a cloud-based container deployment and management service. It supports open-source tools and technologies for container and its orchestration.
It is a flexible, open-source, and simple service to run your container applications in the cloud. You can deploy your container-based applications on a framework with just a few clicks.
The framework is designed to help manage the container’s complexity deployed at a scale in production. Azure Container Service will offer two options to choose from popular orchestration engines: DC/OS or Docker Swarm.

Azure Cognitive Service

Azure Cognitive Service provides a family of AI Services Cognitive APIs for the developers. There isn’t a need to be an expert in machine-learning.
It will let you build apps with powerful algorithms using a few lines of code.
Azure Cognitive Service allows you to deploy Cognitive Services anywhere from the cloud. They work over various devices and platforms like iOS, Android, and Windows.

Azure Container Registry

Azure Container Registry is a registry of Docker and Open Container Initiative (OCI) images. It supports all OCI artifacts.
There are various methods to deploy Azure Contain Registry. The easiest method is using the Azure Portal.
With features like Geo-Registry, it is possible to manage a single registry over multiple regions. It provides integrated security with Azure Active Directory (AD).
Azure Contain Registry handles private Docker images as well as related content formats to provide fast, scalable retriever of container workloads.

Azure Application Insights

Azure Application Insights is a feature of Azure Monitor. It’s an Application Performance Management (APM) service for web developers that supports multiple platforms. It is mainly used by DevOps professionals.
It will automatically detect performance exceptions. It also includes analytics tools to help you diagnose the issues.
To enable Application Insights, you can install an SDK in your application or use Application Insights Agent.

Azure Key Vault

As the name suggests, the Azure Key Vault is a tool to store and access secrets in a protected way. A secret could by anything confidential. Such as API keys, passwords, or certificates.
To do any operations with Keyo Vault, you need to authenticate it first.
There are three ways for that: Managed identities for Azure resources, Service principal and certificate, and Service principal and secret.
Azure Key Vault provides the benefits of a Hardware Security Model (HSM) without the headache of managing it.
