As organisations increasingly transition to the cloud, the synergy between open source and cloud technologies has become ever more evident. Let’s delve into how open source platforms are reshaping the cloud computing landscape and offering new possibilities for innovation, efficiency, and security.
Open source cloud platforms are built on principles of open collaboration and transparency. They allow users to access, modify, and distribute the source code, which facilitates customisation and ensures that the platforms evolve to meet diverse needs. This approach contrasts with proprietary platforms, where users are often limited to the features and capabilities provided by the vendor.
Benefits of open source cloud platforms
Cost savings: Open source platforms eliminate the licensing fees associated with proprietary software. Organisations can deploy these solutions with minimal upfront costs and pay only for the resources they use.
Flexibility and customisation: Users can modify the source code to tailor the platform to their specific requirements. This flexibility enables the integration of new features and optimisations that align with unique business needs.
Community support: A vibrant community of developers and users contributes to the ongoing improvement and support of open source cloud platforms. This community-driven approach ensures that issues are addressed quickly and innovations are incorporated into the platform.
Examples of open source cloud platforms
OpenStack: This leading open source cloud platform is designed for building and managing cloud infrastructure. It provides a comprehensive suite of services, including compute, storage, and networking, allowing users to create private or public clouds.
Apache CloudStack: An open source cloud computing platform for creating and managing large-scale cloud environments, it offers features for compute, storage, and network management, with a focus on ease of use and scalability.
OpenNebula: A flexible open source platform for building and managing private, public, and hybrid clouds, it provides a unified view of cloud resources and supports various virtualisation technologies.
Serverless computing and open source
Serverless computing represents a transformative shift in cloud architecture, enabling developers to build and run applications without managing server infrastructure. In this model, the cloud provider handles server provisioning, scaling, and maintenance, allowing developers to focus solely on writing code.
Serverless computing allows applications to be broken down into individual functions or services that execute in response to events or triggers. These functions run in stateless, ephemeral environments, scaling automatically based on demand. This model contrasts with traditional server-based computing, where developers must manage servers, handle scaling, and ensure high availability.
The benefits of serverless computing are:
Reduced operational overhead: Developers are relieved from the burden of managing servers and infrastructure, leading to faster development cycles and reduced operational complexity.
Automatic scaling: Serverless platforms automatically scale resources based on the volume of incoming requests, ensuring optimal performance without manual intervention.
Cost efficiency: Users pay only for the compute time consumed by their functions, which can result in significant cost savings compared to provisioning dedicated servers.
Imagine a company that needs to process user-uploaded images in real-time. With serverless computing, it can deploy a function that is triggered whenever a new image is uploaded. The function processes the image (e.g., resizing, filtering) and stores the result in a cloud storage service. This approach eliminates the need for dedicated servers and scales automatically based on the volume of image uploads.
Open source serverless platforms
The rise of serverless computing has also been embraced by the open source community, leading to the development of various open source serverless platforms that offer benefits similar to proprietary solutions.
Apache OpenWhisk: Apache OpenWhisk is an open source serverless platform that provides a framework for building and deploying serverless applications. It supports multiple programming languages and allows developers to define functions, triggers, and actions.
Kubeless: Kubeless is another open source serverless platform designed to run on Kubernetes. It integrates with Kubernetes to manage serverless functions and offers features such as automatic scaling and event-driven execution.
Cloud security and open source
As organisations increasingly adopt cloud computing, security concerns become paramount. Cloud environments are susceptible to various threats, including data breaches, misconfigured access controls, and unauthorised access. Open source tools play a crucial role in addressing these challenges by offering transparency, customisation, and robust security features.
Common security threats are:
Data breaches: Unauthorised access to sensitive data can occur due to weak security practices or vulnerabilities in cloud infrastructure.
Misconfigured access controls: Incorrectly configured permissions and access controls can expose data and services to unauthorised users.
Insider threats: Employees or contractors with access to cloud resources might misuse their privileges or inadvertently compromise security.
Ensuring robust security in cloud environments is essential for protecting sensitive data, maintaining regulatory compliance, and safeguarding the integrity of cloud-based applications. Implementing effective security measures helps prevent data breaches, avoid financial losses, and preserve organisational reputation.

Cloud management and optimisation with cloud orchestration
Cloud orchestration is a critical component in managing complex cloud environments. It refers to the automated management of cloud resources and services, and involves integrating various cloud services, such as compute, storage, and networking, into a cohesive system that operates efficiently and reliably. Orchestration tools help automate repetitive tasks, manage dependencies, and enforce policies, leading to improved operational efficiency and reduced human error. The benefits of cloud orchestration are:
Improved efficiency: Automation of repetitive tasks, such as provisioning resources and scaling applications, reduces manual intervention and speeds up operations.
Consistent deployment: Orchestration ensures consistent deployment of applications and services, minimising configuration errors and ensuring that all instances are deployed with the same settings.
Resource optimisation: By automating resource allocation and scaling, orchestration tools help optimise resource usage, leading to cost savings and better performance.

Data management in the cloud
Effective data management is crucial for maintaining data integrity, security, and accessibility in the cloud. Adopting best practices helps organisations optimise data storage, ensure compliance, and protect against data loss.
Data backup and recovery: Regular data backups and robust recovery mechanisms are essential for protecting against data loss and ensuring business continuity. Automated backup solutions and test recovery procedures must be implemented periodically to verify their effectiveness.
Data encryption: Encrypting data both at rest and in transit is vital for protecting sensitive information from unauthorised access. Encryption services provided by cloud providers should be utilised and best practices followed for key management.
Data governance: Data governance policies must be implemented to ensure data quality, consistency, and compliance with regulatory requirements. Data ownership, access controls, and data lifecycle management practices should be defined.
Cost management: Data storage costs should be monitored and optimised by using cost-effective storage solutions and implementing data lifecycle policies to manage data retention and archival.
