Developer Guide

Single-Tenancy

Our IoT platform will also act as a single tenancy for the customer who wants to implement the IoT platform and has a stand-alone server.

Multi-Tenancy

Our IoT platform has SaaS-based, multi-tenancy architecture which helps the user to serve multiple customers. Using this architecture, users or service providers can deploy the IoT platform in a single instance and give individual web access for each customer to share the resource from the single instance. Also, we provide an Admin console for the provider to monitor each customer and their device.

For example, a Home automation provider will implement their sensor kit in multiple customer’s homes. If the provider implements a stand-alone platform for each customer, then it will increase maintenance & development cost and also make monitoring harder. To overcome this, the provider can deploy our platform in the cloud server and give web access or login for each customer. Individual web access helps customers to monitor their device individually and also resources like databases etc are shared from the single instance which will save cost and time.

User Authentication Using SSO

SSO is an integration of Identity and Access Management(IAM) from a common server that permits a user to use one set of login credentials like Username and Password to securely access multiple websites and applications.

SSO for User Login:

• When the client login to the IoT platform the SSO tool demands an encrypted token from the authentication server.
• Then the SSO will receive the user id and token from the identity provider and assign it to the approaching clients.
• Now, the SSO will retain the details to the IoT platform.
• Once the authentication is verified the client will be logged into the IoT platform using the SSO through the Rest API.

SSO Third-party providers in IoT Platform :

In IoT Platform we are utilizing two standard third-party providers.

• OAuth
• OAuth 2.0

OAuth:

• It is a token-based authentication that is used to provide SSO and permits information to be utilized by third party services.
• It likewise requires an identity provider for authenticating clients access.
• In IoT Platform, OAuth is used to communicate different servers/client’s own servers like google home, Amazon smart home, etc.

OAuth 2.0:

• It authorizes third-party applications to access the client account.
• It authenticates the client by following the authorization code flow.
• OAuth 2.0 provides authentication flows for web applications, desktop applications, and mobile devices.

Device Authentication via IAM

IAM is a solution to securely manage digital identities, software’s and hardware’s and their access to various applications and systems. It reduces the risks of identity fraud and improves the collaboration between the users.

IAM for Device Login:

For a device connection, the device will be registered by the user in the IAM tool via the IoT platform.

• From the IAM tool, the ID and token for the device will be generated for connection. The device will be requesting the token from the IAM Tool.
• The device will now use the ID and the token to connect to the IOT Platform.
• The IOT Platform has been built with hooks with which any IAM token provider can be integrated to the Edge device authentication flow.
• Once the authentication details are valid and the device will be allowed to connect to the Platform.

Self-healing

There are two methods to configure Kubernetes to manage containers, where platform depend will run. The two methods are

• Restart Always – This method will take a replica or backup when starting a container and its functions. So, when the container fails, it will automatically create a new container with the backup and restart the service.
• Never Restart – This method does not take any backup of containers and when the container fails, it remains in an inactive status and Kubernetes will not restart it.

We will deploy the Kubernetes console with “Restart Always” method. With this method, Kubernetes will take the backup of each container. So, when the container fails the Kubernetes will automatically create a new container and load the backup and restart the service.

Horizontal Scaling

Kubernetes observe each container CPU usage and automatically scale up or down based on CPU usage. When the platform service uses 80-90% CPU, then Kubernetes automatically create a new pod or container, then loads the service from deployment and runs the created pod, this will help service to scale up based on CPU usage. Also, when the container uses minimum usage, then Kubernetes scale down the pods based on usage. This setup will help the Bevywise IoT Platform to scale up when millions of millions connected.

Alert Configuration

Humans can’t monitor each service and platform for 24X7. So, if any container reaches its maximum CPU level or memory level, then the container will hang and stop all the services running inside it. In such cases, we should configure an Alert and notification based on CPU usage, Memory usage, etc.

To configure alert and notification, we use Grafana set up in which we will set up a separate alert panel to create alert and for notification, we will create a notification channel.

In the Notification channel, you can select any notification type like Email notification, telegram notification, etc. Once you have done, the alert will be automatically sent to your selected notification type.

In Alert panel, you can set certain limit in percentage or memory unit with condition check for CPU usage, Memory or RAM usage, CPU core usage, and Disk usage. So, when the condition is satisfied, an alert be will sent to users via notification type
