Scaling Your App Doesn’t Have to Mean Scaling Your Team

Scaling your app doesn’t mean you need to expand your team. By leveraging managed services, automation, and cost-saving strategies, small and medium-sized businesses (SMEs) can handle growth efficiently. Here’s how:

• Managed Services: Outsource tasks like server maintenance, database management, and security to save time and reduce downtime.
• Infrastructure-as-Code (IaC): Automate cloud deployments and configurations, cutting errors by 50% and deployment failures by 60%.
• Cloud Cost Optimisation: Use reserved or spot instances and refine resource usage to reduce unnecessary expenses, saving up to 90% in some cases.
• Improved Monitoring: Proactive alerts and AI-driven anomaly detection prevent outages and streamline incident response.
• Developer Efficiency: Automate CI/CD pipelines and provide self-service tools to eliminate bottlenecks and improve productivity.

10 Ways to Use No Code and Automation to Scale as a Solopreneur

Using Managed Services to Reduce Operations Work

Managed services take care of essential cloud infrastructure tasks, allowing your team to concentrate on building features rather than maintaining servers. For lean teams scaling an app, every hour spent on server upkeep is an hour that could have gone into product development. The challenge lies in knowing which operational tasks to outsource and which to keep in-house. This decision becomes especially important as you evaluate which parts of your infrastructure are worth outsourcing for greater efficiency.

"For small businesses, adopting cloud services makes a lot of sense...This means businesses can avoid the cost and hassle of managing their own data centres and servers."
– Katie Malaebeh, Head of Marketing, Yo Telecom

Managed services help reduce the maintenance burden across your cloud environment. They provide proactive monitoring, automatic updates, and strong security measures to safeguard your infrastructure. For growing teams, these services are especially valuable because they ensure compliance with regulations and handle change and incident management, reducing the chances of outages or disruptions.

One of the standout benefits is cost savings. Managed services can cut IT expenses by 25–45%, freeing up funds for other growth-focused initiatives. These savings come from eliminating the need for dedicated infrastructure staff, reducing downtime through proactive monitoring, and automating resource optimisation.

When Managed Services Make Sense

Managed services are particularly effective for essential infrastructure that needs to be dependable but doesn’t directly set your product apart. The goal is to focus your team’s efforts on areas where their time has the most impact.

Database management is a prime candidate for outsourcing. Instead of spending hours fine-tuning PostgreSQL settings or managing Redis clusters, managed database services handle scaling, backups, and performance adjustments automatically. This is especially crucial during traffic surges when your team can’t afford to divert resources from core development.

Another area where managed services shine is serverless platforms. These platforms handle scaling, security updates, and infrastructure provisioning without requiring in-depth DevOps expertise. For UK-based SaaS companies dealing with fluctuating traffic, serverless solutions can scale seamlessly from zero to thousands of requests without manual intervention.

Security and compliance are also strong arguments for managed services, especially for UK businesses managing customer data. With GDPR regulations and increasing cyber threats, managed security services offer 24/7 monitoring and incident response. Building this level of security in-house would be prohibitively expensive, but these services provide automated compliance management and reduce operational risks.

"Organisational IT decisions are made based upon business goals, the choice to use a managed service or self-hosted solution will depend on this. There is no 'one size fits all' answer, and ultimately whether you choose to self-host or get a managed service will depend on your business' unique requirements."
– Responsiv

Timing plays a crucial role. Managed services are most beneficial during periods of rapid growth when you lack the time or budget to hire specialised infrastructure engineers. They’re also valuable when your team doesn’t have the expertise for tasks like database optimisation or security hardening.

Managed vs Self-Hosted: Side-by-Side Comparison

Choosing between managed and self-hosted solutions requires a clear understanding of your team’s priorities and resources. Most businesses find success with a hybrid approach, combining the strengths of both options. Here’s a quick comparison:

The trade-offs often come down to data control and flexibility. Self-hosting offers complete control over your applications and data, enabling custom solutions without the limitations of service-level agreements. On the other hand, managed services involve third-party access but provide expertise and resources that might not be available internally.

Reliability is another key factor. Managed services minimise downtime with proactive monitoring and clear service-level agreements. In contrast, self-hosted solutions require your team to ensure uptime, which can be demanding without dedicated infrastructure expertise.

For many UK small and medium-sized businesses scaling their applications, a hybrid approach strikes the right balance. Retain control over core business logic and customer-facing features, where customisation is critical. At the same time, use managed services for infrastructure components like databases, monitoring, and security. This approach lets your engineering team focus on what makes your product stand out, while ensuring your infrastructure remains stable and scalable as you grow.

Automating Infrastructure with Infrastructure-as-Code

Infrastructure-as-Code (IaC) takes automation a step further by simplifying deployments and reducing the operational burden. Instead of relying on manual commands, IaC enables small teams to manage their cloud environments through code. With this approach, your entire infrastructure is defined in code files, which can be version-controlled, reviewed, and deployed automatically. This eliminates the reliance on a single expert to configure servers, databases, or networking.

With IaC, configuration errors can drop by 50%, and deployment failures by 60%, significantly lowering the chances of late-night emergencies while freeing up time to focus on building new features.

"A developer wouldn't write every line of code each time they had to run their application. Similarly, an operations engineer shouldn't have to click through every button in their cloud provider each time they want to deploy a new environment. They must be able to store everything that defines their Infrastructure as Code. This is generally stored in something like GitHub - the same place that developers maintain their app code."
– Briana Frank, director of product management for IBM Cloud

Two popular tools in this space are Terraform and Pulumi. Terraform uses HashiCorp Configuration Language (HCL), a syntax tailored for managing infrastructure. Pulumi, on the other hand, allows teams to use familiar programming languages like Python, TypeScript, or Go. This makes it easier for development teams to contribute to infrastructure tasks without learning a new syntax. Pulumi also shines with features like Dynamic Provider Support, which speeds up support for new cloud resources compared to Terraform. Additionally, Pulumi encrypts secrets by default, while Terraform requires external tools like Vault for secure secret management.

How to Implement Infrastructure-as-Code Properly

To implement IaC effectively, treat your infrastructure definitions as you would application code.

"Infrastructure should be defined as code and treated in the same way as application code."
– Home Office

Store these definitions in version control systems, ensuring peer reviews catch potential issues before they reach production. This practice not only improves reliability but also spreads knowledge across the team. Break your infrastructure into reusable modules rather than relying on large, unwieldy files. For instance, you could create a module for a standard web application setup that includes a load balancer, an auto-scaling group, and a database. This modular approach helps maintain consistency across environments and reduces the risk of configuration drift.

Validate your infrastructure definitions before deployment. Tools like Terraform and Pulumi offer built-in validations, and you can enhance this process by integrating automated tests into your CI/CD pipeline. These tests can identify misconfigurations, naming conflicts, or policy violations early in the process. Also, avoid embedding secrets directly in your infrastructure code. Using dedicated secrets management tools ensures sensitive information stays secure.

Cut Manual Work Through Automation

Integrating IaC with CI/CD pipelines brings automation and consistency to your deployments. When developers push updates to an application, the same pipeline can automatically refresh the infrastructure as needed. This ensures that your environment evolves alongside your application.

Automated tools can continuously monitor for configuration drift, saving countless hours of manual work. Instead of painstakingly setting up new environments, your team can deploy complete infrastructure stacks in minutes. Organisations using IaC report saving up to 30% on operational costs annually. These savings come primarily from reduced maintenance and fewer configuration errors.

Security should also be part of your automation strategy. Incorporate automated security scans into your deployment process to catch issues like overly permissive access controls or unencrypted storage before they become major problems. Additionally, using Policy as Code helps enforce your organisation's security and compliance standards automatically - a crucial practice for UK businesses managing GDPR requirements.

Start by automating routine tasks, and as your team grows more confident, expand your use of IaC to maximise these benefits.

Cutting Cloud Costs While Keeping Performance

Cloud expenses can spiral out of control if left unchecked. According to McKinsey, businesses have seen their cloud costs grow by an average of 25% to 30% annually. Even more troubling, around 30% of global cloud spending is believed to be completely unnecessary. For UK-based SMBs and scaleups, this kind of inefficiency could mean the difference between sustainable growth and burning through their financial runway.

Here’s the good news: cutting cloud costs doesn’t have to mean compromising performance. With smart strategies, you can reduce your expenses while keeping your applications running efficiently.

Proven Ways to Save on Cloud Bills

Lowering your cloud costs can be as straightforward as refining your operations. Here are some tried-and-tested methods to achieve savings without sacrificing performance:

• Rightsizing your resources: Start by analysing your usage data. If your applications consistently use less than the allocated capacity, it might be time to scale down. By aligning your resources more closely with actual demand, you’ll avoid paying for unused capacity while keeping everything running smoothly.
• Reserved instances: For predictable workloads, committing to reserved instances can result in significant savings. For example, AWS Reserved Instances can save up to 75%, while Google Cloud’s Committed Use Discounts offer savings of up to 57%. Although these require a longer-term commitment, they can be a game-changer for businesses with steady compute needs.
• Spot instances: Perfect for batch jobs, development, or CI/CD tasks, spot instances can slash costs by up to 90% compared to on-demand pricing. If your workloads are flexible, this is an excellent way to save big.
• Automated scheduling: Non-production environments, like development and staging, often don’t need to run 24/7. By automatically shutting these down outside business hours, you can eliminate unnecessary costs.
• Storage optimisation: Often overlooked, storage costs can be trimmed by moving infrequently accessed data to cheaper storage tiers. Regularly deleting outdated backups and snapshots can also help reduce your bills.

Track Spending and Catch Cost Spikes Early

Keeping a close eye on your cloud expenses is essential. Setting up budget alerts at 50%, 80%, and 100% of your monthly spend ensures you’re notified when spending approaches critical thresholds. When engineers see the direct financial impact of their choices, they’re more likely to make cost-conscious decisions.

Accurate tagging and anomaly detection can pinpoint where your money is going. By labelling resources by environment (e.g., production, staging), team, or project, you can easily identify unnecessary expenses - like an old proof-of-concept database that’s still running. Tools from cloud providers, such as AWS Cost Anomaly Detection, Azure Cost Management alerts, and Google Cloud’s budget alerts, are invaluable for spotting spending spikes early. For example, in 2023, Tyler Technologies saved approximately £960,000 annually by implementing strong cloud cost governance.

Real-time monitoring tools go a step further by offering deeper insights than standard dashboards. These platforms can identify underused resources, suggest rightsizing options, and even predict future costs based on current trends. While some tools provide automated optimisation, manual reviews are still critical to ensure performance isn’t compromised.

Better Monitoring and Incident Response

When scaling operations, having strong monitoring and incident response systems is critical. While automated infrastructure and cost management lay the groundwork, monitoring needs to go beyond just confirming uptime - it must diagnose and explain problems. For smaller teams, this might feel daunting, but with a well-thought-out strategy, monitoring and incident response can actually reduce the day-to-day workload.

The stakes are high: 39% of UK businesses reported experiencing at least one cyber-attack in the past year. On top of that, a single hour of unplanned downtime can cost up to £1.8 million. These figures highlight why monitoring systems should not only detect problems but also enable proactive management to address them before they escalate.

Setting Up Monitoring That Delivers Results

For smaller teams, effective monitoring revolves around turning data into actionable insights. This involves leveraging logs, metrics, and traces:

• Logs: Provide details on what happened during specific events.
• Metrics: Track changes in system performance over time.
• Traces: Map the journey of requests through your system to pinpoint issues.

The key is to adopt a data-driven approach - collect the right telemetry and focus on transforming this data into meaningful insights. For instance, Netflix shifted to smarter monitoring, which allowed the company to scale rapidly without compromising performance.

Set up threshold alerts to flag unusual activity and integrate AI for anomaly detection. This can help identify patterns and potential issues before they become major problems. Take Zambon, an Italian healthcare company, as an example. By partnering with cloud-native monitoring tools, they developed a shared platform for 16 websites, cutting setup costs for new sites by 55%.

Choosing the right tools is also crucial. Open-source options like Prometheus and Grafana offer flexibility and a strong community for support. On the other hand, cloud-native tools such as AWS CloudWatch, Azure Monitor, or Google Cloud Monitoring provide seamless integration with their respective ecosystems. The choice often depends on your team’s resources and expertise.

In-House vs Outsourced Incident Response

Once monitoring is in place, the next step is to establish a reliable incident response system. Here, teams face a choice: manage it in-house or outsource the responsibility.

• In-House Teams: Your engineers will have a deep understanding of your systems, enabling faster decision-making. However, this approach requires significant investment in training, tools, and establishing 24/7 coverage, which can strain smaller teams.
• Outsourced Teams: External providers bring expertise, established processes, and round-the-clock coverage. While they may need time to get familiar with your specific setup, outsourcing allows your team to stay focused on core product development.

For many smaller teams, a hybrid approach works best. Start by outsourcing incident response for immediate, reliable coverage, and gradually build internal capabilities as your team grows.

Consider the example of IT consultancy firm ilionx. They implemented cloud-native monitoring tools to automate network traffic management on their Kubernetes platform. This not only boosted network security and insights but also enabled them to collect 500,000 data points daily.

"We chose the cloud-native approach, rebuilding virtually all of our technology and fundamentally changing the way we operate the company... It took time and effort to transform Netflix into a cloud-native company, but it put us in a much better position to continue to grow and become a global TV network."
– Yury Izrailevsky, Vice President, Cloud and Platform Engineering at Netflix

Making Developer Workflows More Efficient

Streamlining developer workflows is a key strategy for scaling teams without increasing headcount. Developers often lose valuable time on repetitive tasks like manual deployments, environment setups, and code quality checks. These inefficiencies not only waste time but also divert attention from building features that add value to the business. Considering that engineers are often among the most expensive resources in a company, having them wait for builds or manually resolve issues can significantly drag down productivity. Addressing these inefficiencies is essential to removing bottlenecks and optimising the entire development lifecycle.

Automate CI/CD Pipelines and Code Reviews

Automation has the power to transform development workflows by eliminating delays and improving overall software delivery. Automated CI/CD pipelines catch bugs early, maintain code quality, and free developers to focus on solving complex challenges. Automated testing rejects faulty builds, while automated deployments minimise human error, ensuring only production-ready code moves forward.

"The #1 way you can optimise your CI/CD pipelines is to identify and leverage tools that reduce the amount of work that your developers have to invest in building and maintaining your CI/CD pipelines. Tools that replace manual steps for environment creation, deployment and testing with simple commands can have an outsized impact on the overall experience building and maintaining the pipelines, allowing for more time to be focused on other tasks." - Kai Tillman, Senior Engineering Manager, Ambassador

Studies reveal that smaller pull requests (around 500 lines of code) are three times more likely to receive thorough reviews than larger ones (e.g., 2,000 lines). Automated linters can handle routine code quality checks, while checklist-based code reviews have been shown to improve defect detection rates by over 66.7%. Additionally, the ideal code review session should last no more than 60 minutes, as reviewer focus tends to decline after examining 400 lines of code. By automating these routine checks, teams can keep reviews sharp and effective.

Another way to improve workflows is by grouping related pull requests for parallel work. Tools like Graphite simplify managing dependencies between pull requests, enabling developers to work on multiple features simultaneously without waiting for sequential approvals. With efficient deployments and focused code reviews, teams can innovate faster and more effectively.

Give Developers Self-Service Tools

Beyond automation, self-service tools empower developers to manage resources independently, cutting down on delays caused by waiting for operations teams. Internal Developer Platforms (IDPs) bring together tools, resources, and documentation into a centralised hub, enabling developers to handle infrastructure tasks like deployments and monitoring on their own. This independence not only reduces wait times but also allows teams to move at their own speed.

Self-service tools such as Infrastructure as Code (IaC) platforms (e.g., Terraform, OpenTofu) and configuration management tools like Ansible simplify resource provisioning and reduce the likelihood of manual errors. Ansible, for instance, uses a YAML-based syntax that is easier to work with compared to alternatives like Chef or Puppet.

Container orchestration platforms add another layer of self-service capability. Choosing the right platform depends on your team’s expertise and scaling requirements.

"Empowering development teams with self-service and automation capabilities has long been a goal for organisations seeking to reduce bottlenecks and speed up innovation." - Markus Eisele, Red Hat developer tools marketing leader

Real-world examples highlight the effectiveness of this approach. Spotify’s Backstage, for instance, allows platform teams to create custom internal developer portals, integrating tools, services, and documentation into a single hub. Similarly, Quali Torque serves as an internal developer platform for managing the lifecycle of complex cloud infrastructure.

That said, simplicity is crucial. As Shannon McFarland from Cisco points out, if the dependency chain isn’t designed as a cohesive "stack", developers may find themselves navigating complex domains like cloud, networking, and security. The best self-service tools abstract this complexity while remaining flexible.

A great starting point is using version control systems like GitHub or GitLab for centralised code management, change tracking, and integrated CI/CD workflows. From there, you can incorporate cloud provider tools that allow developers to provision resources independently, eliminating the need for lengthy approval processes.

Conclusion: Smart Scaling for Long-Term Growth

Scaling your application without increasing your team size isn’t just achievable - it’s a smart move for ensuring sustainable growth, especially in today’s competitive environment. The strategies discussed in this guide provide UK-based SMBs with practical ways to maximise existing resources while keeping costs and reliability in check.

Managed services are a cornerstone of efficient scaling. By outsourcing tasks like database management, server upkeep, and infrastructure maintenance, your engineers can focus on developing features that drive revenue, rather than getting bogged down in operational tasks.

Infrastructure-as-Code (IaC) simplifies scaling by automating deployments, reducing manual errors, and ensuring consistency. This means your team can roll out updates or scale systems confidently, without requiring additional staff or round-the-clock manual oversight.

Cost optimisation is crucial as your application grows. In 2023, UK businesses faced significant losses - £21.3 billion from internet outages alone. Tools like Kubecost, AWS CloudWatch, and Azure Cost Management help pinpoint areas of waste, such as unused resources or overly large infrastructure. Simple steps like clearing outdated backups, adjusting retention policies, and using cloud provider savings plans can make a big financial difference without sacrificing performance. Consider this: downtime can cost UK SMBs anywhere from £500 to £5,000 per hour, and the average cyber breach racks up costs of £25,700. Reducing unnecessary expenses not only saves money but also frees up resources to invest in innovation.

Streamlined workflows play a key role in boosting productivity. Automated CI/CD pipelines and self-service tools empower developers to work independently, cutting down on delays and increasing efficiency. When developers can provision resources or deploy code without waiting for manual approvals, project timelines shrink, and output improves.

The best scaling strategies don’t rely on a single solution. Instead, they integrate multiple approaches - managed services, automated infrastructure, cost monitoring, and workflow optimisation - to create a resilient and agile system. This blend ensures your business can adapt quickly and stay competitive in a rapidly evolving market.

FAQs

How can small and medium-sized businesses decide which tasks to manage internally and which to outsource to managed services?

SMBs can benefit greatly by outsourcing routine, non-core tasks like IT maintenance, system monitoring, or payroll. These are the kinds of responsibilities that, while necessary, don’t directly contribute to business growth. By outsourcing them, your team can focus on what truly matters - driving innovation and achieving strategic goals.

When making outsourcing decisions, think about factors such as cost-effectiveness, the level of expertise required, how much control over operations is necessary, and the strategic value of the task. Outsourcing can help cut down on operational costs, but keeping core processes in-house ensures your business stays agile and aligned with its objectives.

How can Infrastructure-as-Code (IaC) help small teams manage their cloud environments more efficiently?
