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
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.
Amazon DynamoDB is a managed NoSQL database service provided by Amazon Web Services (AWS). It is designed to provide high availability, scalability, and performance for applications that require fast and predictable performance with seamless scalability.
Key features of Amazon DynamoDB include:
Managed Service: DynamoDB is fully managed by AWS, which means AWS takes care of tasks such as hardware provisioning, software patching, setup, configuration, and backups. This allows developers to focus on building applications rather than managing the database infrastructure.
NoSQL Database: DynamoDB is a NoSQL database, meaning it does not use a fixed schema and can handle semi-structured or unstructured data. It uses a flexible data model to store and retrieve data in the form of items, which are similar to rows in a traditional relational database.
High Availability and Durability: DynamoDB offers built-in data replication and automatic multi-data center synchronization, ensuring high availability and data durability. It replicates data across multiple Availability Zones within an AWS region.
Scalability: DynamoDB can handle large amounts of traffic and data. It offers automatic scaling based on the application's needs, and it can handle sudden spikes in traffic without manual intervention.
Predictable Performance: DynamoDB provides low-latency, predictable performance, with the ability to define read and write capacity units. It also supports on-demand capacity for unpredictable workloads.
Rich Query Capabilities: DynamoDB supports powerful querying capabilities with secondary indexes, allowing efficient retrieval of data using various attributes.
Security and Access Control: DynamoDB integrates with AWS Identity and Access Management (IAM) for access control and provides encryption at rest and in transit.
Integration with Other AWS Services: DynamoDB can be easily integrated with other AWS services, such as AWS Lambda, Amazon S3, Amazon Redshift, and more, to build comprehensive and scalable applications.
Amazon DynamoDB is commonly used for various applications, including web and mobile applications, gaming, IoT (Internet of Things), real-time analytics, and more, where high performance, scalability, and ease of management are important considerations.
