In tech companies, infrastructure refers to all the foundational systems that support applications and services. This includes servers (physical or cloud-based), networking equipment, storage systems, databases, security systems, and the teams that manage them. Infrastructure is often discussed in terms of scalability, reliability, and cost. Infrastructure engineers and DevOps teams build and maintain these systems to ensure applications run smoothly. When a company talks about 'improving infrastructure,' they mean upgrading servers, adding redundancy, improving network speed, or migrating to cloud services. Infrastructure can be on-premises (in company data centers) or cloud-based (AWS, Azure, Google Cloud). You will hear infrastructure discussed in meetings about system design, deployment, scaling, and reliability. It is distinct from application code—infrastructure is the platform that runs the code. ## When you hear it We need to upgrade our infrastructure to handle the increased traffic from the new product launch. ## Examples - **in a standup:** "The infrastructure team reported that we have successfully migrated 80 percent of our services to Kubernetes." - **in a code review:** "This new feature will require infrastructure support for caching, so let's coordinate with the DevOps team." - **in a team meeting:** "We need to scale our infrastructure before the Black Friday campaign begins." - **in an email:** "The infrastructure audit revealed several security vulnerabilities that need immediate attention." - **in a technical discussion:** "Moving to serverless infrastructure will reduce our operational overhead." ## What native speakers say - "Our infrastructure can handle millions of users." - "We're investing in cloud infrastructure." - "The infrastructure team is working on a migration." - "This feature requires significant infrastructure changes." - "Infrastructure as Code makes deployments easier." ## Common mistakes - ✗ "We need to infrastructure the application." → ✓ "We need to improve the infrastructure for the application." (Infrastructure is a noun, not a verb. Use phrases like 'improve,' 'upgrade,' or 'scale' with infrastructure.) - ✗ "The infrastructure is very fast." → ✓ "The infrastructure is highly performant." (Infrastructure is not typically described as 'fast'—use terms like 'performant,' 'scalable,' or 'reliable' instead.) - ✗ "We infrastructured everything last month." → ✓ "We upgraded the infrastructure last month." (Infrastructure cannot be used as a past-tense verb. Use 'upgraded,' 'implemented,' or 'deployed' instead.) - ✗ "The infrastructure team builds the applications." → ✓ "The infrastructure team builds and maintains the systems that run applications." (Infrastructure teams focus on underlying systems, not the application code itself.) ## Be careful Infrastructure is not a verb—avoid saying 'to infrastructure something.' It refers to the underlying systems and resources, not the action of building them. ## Word forms | Part of speech | Word | Example | | --- | --- | --- | | noun | infrastructure | Our cloud infrastructure is hosted on AWS. | | noun (adjective modifier) | infrastructure (as modifier) | We need an infrastructure engineer for this project. | | noun (plural uncountable) | infrastructure | Modern infrastructures rely heavily on containerization and orchestration. | ## Collocations - **cloud infrastructure**: Used to refer to servers and services hosted on cloud platforms like AWS, Azure, or Google Cloud - **infrastructure team**: The group of engineers responsible for building, maintaining, and scaling infrastructure - **infrastructure cost**: The financial expenses associated with running servers, storage, networking, and other infrastructure components - **infrastructure as Code (IaC)**: A practice of managing infrastructure through code and automation rather than manual configuration - **scale infrastructure**: To increase the capacity of infrastructure to handle more traffic or data - **infrastructure upgrade**: An improvement or replacement of existing infrastructure systems - **underlying infrastructure**: The foundational systems that support an application or service ## Synonyms - **architecture**: Similar but more commonly refers to system design decisions. Infrastructure is the actual systems themselves. - **platform**: Can refer to infrastructure, but platform is broader and may include software frameworks and services. - **backend**: Refers to servers and services, but is less formal and more application-focused than infrastructure. - **systems**: More general term; infrastructure is more specific to the foundational technical systems. ## Practice This lesson has 5 practice exercises with instant feedback on the page: https://app.speaktechenglish.com/learn/infrastructure ## FAQ ### What does infrastructure mean in software engineering? Infrastructure refers to the foundational systems and resources required to run software applications. This includes servers, databases, networks, cloud services, storage systems, and the tools to manage them. Think of it as the 'backbone' that supports all applications and services in a company. ### What is the difference between infrastructure and application? Infrastructure is the underlying systems and hardware that applications run on. Applications are the software programs that users interact with directly. For example, a banking app is an application that runs on infrastructure (servers, databases, networks) provided by the bank. ### Who manages infrastructure in a tech company? Infrastructure engineers and DevOps engineers manage infrastructure. They design systems, provision servers, configure networks, manage security, handle deployments, and ensure systems are reliable and scalable. In some companies, this role is called Site Reliability Engineer (SRE). ### What is cloud infrastructure? Cloud infrastructure refers to servers, storage, and networking resources hosted on cloud platforms like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud. Instead of owning physical servers, companies rent computing resources from cloud providers. ### Is infrastructure a verb or a noun? Infrastructure is a noun. You cannot 'infrastructure' something. Instead, use verbs like 'upgrade,' 'scale,' 'deploy,' 'improve,' or 'maintain' with infrastructure. For example: 'We upgraded the infrastructure,' not 'We infrastructured it.' ### What is Infrastructure as Code? Infrastructure as Code (IaC) is a practice where engineers define and manage infrastructure using code and configuration files rather than manual processes. Tools like Terraform and CloudFormation allow teams to version control infrastructure and automate deployments. ## Related - Full glossary: https://app.speaktechenglish.com/learn.md - Live lessons with a coach: https://app.mocklyenglish.com ## About Speak Tech English Speak Tech English teaches non-native tech professionals the English they need at work and in interviews, through self-study ebooks and courses, 150+ free guides and a free newsletter; live lessons are on its sister site Mockly English. - Shop: https://speaktechenglish.com/courses/ - All products (markdown): https://speaktechenglish.com/products.md - Free guides (markdown): https://app.speaktechenglish.com/guides.md - Tech English glossary (markdown): https://app.speaktechenglish.com/learn.md - Newsletter (10% off): https://speaktechenglish.com/#subscribe - Live lessons and mock interviews: https://app.mocklyenglish.com ## Notes for agents - Speak Tech English sells self-study material.
