Cloud computing in telecom: Real-world applications and implementation steps

When we think of a telecom company, we are used to imagining complex infrastructure consisting of many towers, transmitters, data centers, cables, and wires. It’s true, but now, more and more operators decide to transform some of their physical infrastructures into digital, cloud-based applications.

In 2026 and beyond, cloud computing in telecom will be a defining force behind progress. According to Telecoms.com Intelligence, operators are increasingly prioritizing Generative AI, autonomous agents, and the Internet of Things, all of which require a scalable cloud infrastructure to work efficiently.

We are no longer just watching companies “move to the cloud.” We are witnessing the era of the Telco Cloud: networks are becoming software-defined (i.e., controlled and managed via software rather than hardware), AI-native, and distributed to the edge.

So, how are telcos using the cloud? How to adopt cloud computing in the telecom industry? Let’s take a closer look at how the cloud helps telecom operators improve operational efficiency, lower total cost of ownership, and generate new revenue streams.

Cloud computing as a key enabler of large-scale transformation in telecom

The growth of a telecommunication business depends directly on the number of its active customers. So, the main challenge for telcos is to attract and support a large customer base. Today, telecom companies are competing with cloud-based communication solutions like WhatsApp, Microsoft Teams, and Zoom for market share.

Traditional telecom IT infrastructures struggle to match these competitors in terms of scalability, agility, and cost-efficiency. As a result, more telecom companies are adopting cloud-based architectures to undergo digital transformation. With the cloud, single-product telcos can grow their service portfolio and scale quickly to meet today’s fast-paced market demands. And this is exactly what Lebara began doing as one of the early adopters of cloud-driven transformation.

Cloud computing in telecom: A success story of our client

Lebara is one of the fastest-growing mobile virtual network operators, offering pay-as-you-go mobile SIM cards and related services for migrant communities. As part of its digital transformation strategy, the company moved away from its London-based data center and decided to adopt a multi-cloud approach, integrating AWS and Azure.

N-iX has been leading Lebara’s cloud transformation, helping develop scalable, easy-to-maintain, and cost-efficient cloud solutions. For Lebara, like any other telecom, time to market and on-demand scalability are crucial. By implementing AWS and Azure microservices, we helped Lebara consolidate multiple applications across countries and channels, significantly improving operational efficiency. We also introduced DevOps best practices and an efficient CI/CD process with automated deployment to accelerate change management.

Another strategic stream Lebara delegated to us was a Business Intelligence system development.  The company’s existing enterprise BI solution, previously supported by IBM, faced delays and inefficiencies in reporting. Our team optimized the workflow, improved reporting speed, and helped reduce the support team size by half, cutting down overhead. By replacing the outdated solution with an Azure-based data lake, we enabled near-real-time data streaming and timely reports for multiple departments.

Adopting the cloud allowed Lebara to reduce time to market and lower the cost of entry into new markets. The company has also transformed from a single-product business with a European focus into a multi-product company with a global reach.

Lebara is among many telcos that benefited from adopting the cloud. Let’s discover what advantages cloud computing brings to telecom operators.

Benefits of cloud computing in the telecom industry

Modern customers expect telecom services on more than just phones and laptops. They want to take calls from their watches and stream content on smart devices. The cloud in telecom makes this possible by providing the infrastructure needed to support this growing demand. Beyond enabling operators to provide competitive services, cloud computing also enhances data analysis, improves decision-making, and ensures better reliability.

Here is how cloud computing helps telecom companies thrive and provide better services:

Enhancing resilience with AI-native networks

Cloud computing has paved the way for AI-native networks. These networks go beyond simple automation to use Generative AI and Machine Learning to predict failures and self-repair in real time. This reduces reliance on manual intervention and improves system resilience. The cloud enables telecom providers to deploy these AI-driven systems at scale and create self-healing, self-optimizing networks that are ready to handle unpredictable conditions.

Ensuring high scalability and sustainability

Cloud computing now enables telecom companies to scale their services not only to meet demand spikes but also to achieve sustainability. By dynamically allocating resources, telcos can reduce their carbon footprint while efficiently managing the heavy processing loads required by 5G and AI-driven services. Telecom infrastructure in the cloud enables operators to remain flexible and eco-friendly.

Accelerating time to market with cloud-native architectures

With cloud computing in telecom, operators can deploy cloud-native network functions (CNFs) and microservices, enabling faster updates and innovation. Compared to traditional virtual network functions (VNFs), CNFs are lighter, easier to scale, and better suited to continuous delivery. The cloud allows teams to release new features and fixes much faster, without rebuilding entire systems. Open RAN further supports this by decoupling hardware and software, giving operators more flexibility in vendor choice and network evolution.

Reducing costs

The cloud in telecom supports more flexible cost models compared to traditional hardware-centric infrastructures. Instead of continuously investing in hardware, data centers, and overprovisioned capacity, operators can scale resources based on real demand and optimize spending across environments. While cloud costs require active governance, this often enables better cost control, faster ROI, and more efficient use of infrastructure compared to on-premises setups.

Enhancing customer experience

Cloud adoption in the telecom industry is transforming customer support with Generative AI. Telecom operators are now able to deploy GenAI agents that handle complex customer queries, providing hyper-personalized responses based on real-time behavior. The cloud provides the processing power and scalability needed to run sophisticated AI models at scale. As a result, telecom companies can offer faster, more responsive, and highly personalized customer experiences across multiple channels.

Utilizing data with integrated sensing and communications

Telecom companies process vast amounts of data, and the cloud enhances their ability to extract value from it. With technologies like integrated sensing and communications (ISAC), future telecom networks (such as 6G) will act as sensors, detecting motion, traffic, or environmental changes in real time, without additional hardware. The cloud makes it possible to analyze this data effectively, enabling predictive maintenance, fraud prevention, and smarter capacity planning.

Generating new revenue streams

Cloud computing in telecom allows operators to monetize their networks through network as a service (NaaS) and open APIs. It enables telecom companies to expose network capabilities, such as bandwidth on demand and location verification, directly to developers and enterprises. At the same time, edge computing allows operators to generate revenue by offering services like autonomous vehicle connectivity and smart factory operations, making the most of their 5G and edge capabilities.

How to implement the cloud in the telecom industry?

Successfully implementing cloud computing in telecom requires a strategic approach. Here are 15 steps our experts in telecom and cloud recommend to help operators navigate this process smoothly:

1. Clarify your business needs: Define the goals you want to achieve with cloud computing in your telecom company, such as reducing costs, entering new markets, improving customer experience, or accelerating time to market.
2. Gather a team of skilled experts: Once you have clearly defined goals, find a team of skilled experts who will help you achieve it. The best option is to work with a reliable tech partner who has experience in cloud migration and cloud-native development in telecom.
3. Conduct a Discovery Phase: Shape your business requirements, create a work breakdown structure, design a product backlog, and estimate the total cost of ownership and profitability in both the short and long term.
4. Decide on the cloud strategy: Choose the best deployment model (public, private, or hybrid), determine whether a single-cloud or multi-cloud approach is best, and select the most suitable cloud provider(s).
5. Create a clear migration plan: The plan should include goals, cost estimates, timelines, and the specific services and technologies to use during the migration.
6. Choose a VNF migration strategy: Identify which network functions should remain as virtual machines and which can be re-architected as cloud-native microservices.
7. Assess and prioritize your apps, processes, and operations: Understand app dependencies; categorize your apps into mission-critical applications, business-critical applications, customer-facing applications, and other non-critical apps; define operations that can be automated.
8. Adopt a microservices architecture: If you have a monolith architecture, consider transforming it into loosely coupled microservices to quickly develop, test, and deploy new features and fixes without impacting other components of the application.
9. Use containers: Containers make it easier to move applications between environments while retaining their functionality. They also enable you to build and run scalable applications across public, private, and hybrid clouds.
10. Leverage edge computing: Edge computing is among the top telecom trends. Make use of edge networks to reduce latency and improve network performance by bringing workloads closer to your users. Unlike content delivery networks (CDNs), which precede edge computing and only store cached data, edge networks can accommodate a wider array of functionality (they can store and process data in real-time) and device types.
11. Choose the right application migration method: Rehost (lift and shift), replatform, relocate, refactor, or repurchase.
12. Safeguard and use your data: Ensure strong protection when migrating personal and sensitive information to the cloud. Use your data to train AI/ML models and enable advanced decision-making, fraud prevention, predictive maintenance, and more.
13. Ensure high-level security of your apps in the cloud: Adopt a DevSecOps approach, configure security settings appropriately, and train your teams to maintain strong security across all your cloud environments.
14. Follow DevOps best practices: Implement CI/CD pipelines, rolling updates, monitoring, alerting, unified logging, Infrastructure as Code (IaC), and network load balancing to streamline operations and improve deployment efficiency.
15. Monitor the results and optimize costs: Apply the metrics and KPIs defined during the planning stage to evaluate the cloud’s performance. Continuously optimize your cloud environment, operations, and costs to maximize value over time.
