A hyperscaler is a company that provides cloud services on a massive scale — offering IT infrastructure such as computing power, storage, and networking that is flexible, highly available, and globally scalable. Common examples of hyperscalers include:
Microsoft Azure
Google Cloud Platform (GCP)
Alibaba Cloud
IBM Cloud (on a somewhat smaller scale)
Massive scalability
They can scale their services virtually without limits, depending on the customer's needs.
Global infrastructure
Their data centers are distributed worldwide, enabling high availability, low latency, and redundancy.
Automation & standardization
Many operations are automated (e.g., provisioning, monitoring, billing), making services more efficient and cost-effective.
Self-service & pay-as-you-go
Customers usually access services via web portals or APIs and pay only for what they actually use.
Innovation platform
Hyperscalers offer not only infrastructure (IaaS), but also platform services (PaaS), as well as tools for AI, big data, or IoT.
Hosting websites or web applications
Data storage (e.g., backups, archives)
Big data analytics
Machine learning / AI
Streaming services
Corporate IT infrastructure
Puppet is an open-source configuration management tool used to automate IT infrastructure. It helps provision, configure, and manage servers and software automatically. Puppet is widely used in DevOps and cloud environments.
✅ Declarative Language: Infrastructure is described using a domain-specific language (DSL).
✅ Agent-Master Architecture: A central Puppet server distributes configurations to clients (agents).
✅ Idempotency: Changes are only applied if necessary.
✅ Cross-Platform Support: Works on Linux, Windows, macOS, and cloud environments.
✅ Modularity: Large community with many prebuilt modules.
A Puppet manifest (.pp
file) might look like this:
package { 'nginx':
ensure => installed,
}
service { 'nginx':
ensure => running,
enable => true,
require => Package['nginx'],
}
file { '/var/www/html/index.html':
ensure => file,
content => '<h1>Hello, Puppet!</h1>',
require => Service['nginx'],
}
🔹 This Puppet script ensures that Nginx is installed, running, enabled on startup, and serves a simple HTML page.
1️⃣ Write a manifest (.pp
files) defining the desired configurations.
2️⃣ Puppet Master sends configurations to Puppet Agents (servers/clients).
3️⃣ Puppet Agent checks system state and applies only necessary changes.
Puppet is widely used in large IT infrastructures to maintain consistency and efficiency.
Platform as a Service (PaaS) is a cloud computing model that provides a platform for developers to build, deploy, and manage applications without worrying about the underlying infrastructure. PaaS is offered by cloud providers and includes tools, frameworks, and services to streamline the development process.
In summary, PaaS enables fast, simple, and flexible application development while eliminating the complexity of managing infrastructure.
Dev Space is a cloud-based development environment that allows developers to create fully configurable workspaces for software development directly in the cloud. It provides tools and resources to set up a development environment without needing to install or configure software locally.
Dev Space offers a modern solution for developer teams that want to work flexibly and remotely, without the complexity of setting up and maintaining local development environments.
Elastic Compute Cloud (EC2) is a core service provided by Amazon Web Services (AWS) that offers scalable computing capacity in the cloud. With EC2, users can create and configure virtual machines (instances) to run various applications, ranging from simple web servers to complex database clusters.
EC2 provides a wide range of instance types with varying CPU, memory, and networking capabilities to suit different workload requirements. These instances can be quickly launched, configured, and scaled, offering the flexibility to increase or decrease resources as needed.
Additionally, EC2 offers features such as security groups for network security, elastic IP addresses for static addressing, load balancers for traffic distribution, and Auto Scaling to automatically adjust the number of instances based on current demand. Overall, EC2 enables businesses to utilize computing resources on-demand in the cloud, facilitating cost optimization and scalability.
Simple Storage Service (S3) is a cloud storage service provided by Amazon Web Services (AWS), allowing users to store and access data in the cloud. S3 offers a scalable, secure, and highly available infrastructure for storing objects such as files, images, videos, and backups.It operates on a bucket structure, where buckets are containers for the stored objects. These objects can be managed and retrieved using a RESTful API or various AWS tools and SDKs. S3 also provides features such as versioning, encryption, access control, and a variety of storage options that can scale based on the use case.
AWS Lambda is a "serverless" service provided by Amazon Web Services (AWS) that allows developers to execute code without managing or provisioning servers. With Lambda, developers can write functions and upload them to run in the cloud on an as-needed basis without managing infrastructure.
It operates based on "event triggers" that initiate the code, such as uploading a file to an Amazon S3 bucket or receiving a message in an Amazon Simple Queue Service (SQS) queue. Lambda scales automatically to meet the code's demands, and developers only pay for the actual compute power used, as billing is based on the number of function invocations and their duration.
