If you are a Software Application Owner or Manager or Developer then you would agree that, the demands of today’s companies and technology are now better served by cloud-based SAAS systems than by internal IT systems and on-premises solutions.

The Problem

Businesses want to spend less money on managing IT infrastructure, while increasing their responsiveness and agility through outsourced SAAS Solutions. On-premises application development, deployment, and maintenance consume funds, resources, and technical know-how that small companies have in limited supply.

The Opportunity

When it comes to SAAS, for the end-user and end-user company, there is no infrastructure investment needed for a employing a SaaS service. Maintenance and updates are performed by the software vendor; hence the end-user company’s IT resources are more efficiently used for business operations. This makes SAAS a WIN-WIN option for small end user companies and small software application development companies.

The Challenge

However the costs or developing a SAAS application from scratch or to move your current application on LAMP or LEMP or other Stacks to a Development Stack such as Ruby on Rails which supports multi-tenant application development out of the box, could be a daunting and really expensive task.

The Solution

We at IOS have developed a unique solution powered by the seamless integration of cutting-edge technologies like Kubernetes, Rancher, RKE2, K3s, Harvester, AKS,EKS, DOKS, or LKE that will help software development companies harness the power of cloud and Kubernetes to launch their single tenant applications as multi-tenant SAAS solutions on the cloud. We essentially built this approach to launch our own Brands, however, we realized this could be a fabulously useful solution for any software company that would like to:

Transform its single-tenant web application into a multi-tenant SAAS service in the cloud.
Easily launch LAMP, LEMP, Ruby on Rails or other stack based applications for your clients on the Cloud.
Host multiple clients for your software on a single or multi-node kubernetes cluster.
Build Kubernetes on hosting technologies such as vps, vds, dedicated server or on cloud servers such as aws, google cloud.

Launch your Single Tenant Application as a Cloud based Multi-Tenant – Software As A Service (SAAS) solution

We at Infinity Online Solutions (IOS) have over 25+ years of experience in Software technologies. We have built our own SAAS approach based on Kubernetes, Rancher, Multiple Kubernetes Engines, Helm and some custom packages to launch our own brands. We did this as we had multiple brands to launch and doing this with an external party was too expensive.

So, we put together this methodology initially with a combination of hosting based software that enabled us to launch any SAAS brand with a frontend, plans and subscriptions, billing and provisioning, and complete automation of this whole system on a optimal budget.

However the hosting based system needed complex understanding, due to which non-technical users were not able to use this system, to further simplify this process IOS relied on Kubernetes, Rancher, Multiple Kubernetes Engines, Helm and some custom packages to create a seamless SAAS development, deployment, and maintenance Architecture and Approach.

The Kubernetes SAAS approach enables software development teams and IT organizations to launch and deliver robust, reliable and scalable SaaS applications that cater to a diverse range of clients, all while streamlining operations and boosting growth.

Our unique approach allows you to work on features of your Software, while we provide you with support for the development, maintenance, and support of the SAAS functions on Kubernetes, which would essentially include:

  • Kubernetes & Rancher Strategy and Approach
  • Costing and Budgeting of the Kubernetes Services
  • Server Side Technology / Operating Systems
  • Cpanels to Multi Tenant Server at OS and user Level
  • DNS Management to Map domains to Virtual Hosts & Specific Server folders.
  • Provide user wise application development stack for your Application Deployment.
  • User Registration and Subscription Management as per Application Plans
  • Support for Packaging or Packaging of your Application for this environment
  • Application Deployment on user Registration and Payment
  • Application Credentials and Links emails to the Registered user
  • There after the registered user can access your application @ user-n.yoursaaswebsite.com

We provide you with a framework for performing all the multi-tenancy, billing, provisioning and deployment functions, while you continue to develop and manage your core application.

Save Significant Development Cost

This approach enables to slash down your multi-tenant application development costs drastically by as much as 40 – 60% of actually developing a saas based multi tenant application with integrated billing from scratch.

Setup a Rock Solid and Stable Environment

Apart from the cost saving Kubernetes is also a very stable environment built for Cloud by Google and now supported by several technical giants including SUSE, Amazon AWS, Microsoft Azure, RedHat, IBM, Docker. SAAS applications built on a Kubernetes platform enjoy the benefits of reliability, scalability and sustainability.

Save Significant Time and Launch Quickly

Last but not the least, this approach provides you with significant time savings, if your application is ready for the market, then you can launch your application, that can be on a LAMP, LEMP, Ruby on Rails, Apache Kafka, or one of the many stacks available as helm charts, as a SAAS Solutions with this methodology and approach in a fraction of cost that you would spend to re-write your whole application as a Multi-Tenant Application using an appropriate Multi-Tenant Development Methodology.

          9. ⛵ Simplify Deployment with Helm

          Helm is a powerful Kubernetes package manager that allows you to package and distribute your application as a Helm Chart, making deployment globally consistent and automated

          Steps to Package with Helm:

          1. Create a Helm Chart:

          Scaffold a new Helm chart by running:

          helm create your-app

          The directory includes:

            • Chart.yaml: Metadata about your chart.
            • values.yaml: Default application configurations.
            • templates/: Kubernetes manifests rendered using values.yaml.

          2. Customize Templates:

          Modify templates/deployment.yaml to use your Docker image:

          spec:
          containers:
          - name: your-app-container
          image: your-dockerhub-username/your-app-name:latest
          ports:
          - containerPort: 3000

          3. Package the Helm Chart:

          Create a .tgz package for sharing or deployment:

          helm package your-app

          4. Host the Chart for Global Use:

          Publish the Helm chart to a Helm repository (e.g., GitHub Pages or Artifact Hub).

          5. Deploy the Application Globally:

          Install the chart on Kubernetes:

          helm install your-release-name your-app.tgz

          10. 📊 Monitoring, Maintenance and Management

          Set up monitoring for your Kubernetes cluster to ensure performance and reliability using the following tools

          🖥️ On-Prem: Monitoring, Maintenance and Management

          ☁️ Cloud: Monitoring, Maintenance and Management

          Deploy the Kubernetes Dashboard for real-time cluster monitoring and efficient resource management.

          Use cloud-native monitoring tools such as:

          • AWS CloudWatch
          • Azure Monitor
          • GCP Operations Suite

          Universal Monitoring Tools:

          • Prometheus: Metrics collection and alerting.
          • Grafana: Visualization and dashboards.
          • Kube-state-metrics: Kubernetes-specific metrics.
          • ELK Stack: Log monitoring (Elasticsearch, Logstash, Kibana).
          • Loki: Lightweight log aggregation.
          • Jaeger: Distributed tracing for microservices.

          These tools provide robust monitoring and insights into your Kubernetes cluster.

          11. 📈 Test Scalability and Reliability

          • Perform load tests to ensure your SaaS application:
          • Scales efficiently under increased demand.
          • Meets redundancy and failover requirements for high availability.

          12. 🔄 Plan for Continuous Deployment

          Streamline your deployment process and improve reliability with these practices:

          • Use CI/CD Pipelines:
            Automate application deployments to minimize manual errors.
          • Adopt GitOps Tools:
            Tools like Argo CD or Flux can manage Kubernetes configurations directly from your repository

          13. 🖥️ Automate Helm Chart Deployments with Shell Scripts

          Automate deployments to streamline processes and enhance reliability:

          • Automate Helm chart installation, upgrades, and rollbacks.
          • Manage namespaces, configurations, and persistent storage setups

          Example Script:

          #!/bin/bash
          echo "Deploying Application Chart..."
          helm upgrade --install my-app ./charts/my-app --namespace my-namespace -f values.yaml
          echo "Deployment Completed!"

          14. 🐍 Invoke Shell Scripts Programmatically

          Automate deployments to streamline processes and enhance reliability:

          • Automate Helm chart installation, upgrades, and rollbacks.
          • Manage namespaces, configurations, and persistent storage setups

          Example Script:

          import subprocess
          def deploy_application():
          subprocess.run(["bash", "./deploy-app.sh"])
          print("Deployment Triggered!")
          deploy_application()

          15. 🔥 Automate Deployment via Your SaaS Billing Solution

          Use your SaaS billing solution to:

          • Automatically provision Kubernetes resources for new customers.
