The Accelerated Data Science (ADS) SDK is an Oracle-developed Python library that makes common data science tasks faster, easier, and less error prone. The ADS SDK provides tools for data ingestion, exploration, transformation, visualization, modeling, evaluation, interpretation, and deployment. The ADS SDK also integrates with other popular Python libraries such as pandas, scikit-learn, TensorFlow, PyTorch, etc.

The ADS SDK is included as part of the Data Science service at no additional cost. The Data Science service is a fully managed platform that enables data scientists to build, train, deploy, and manage machine learning models on OCI. The Data Science service provides access to notebook sessions that come pre-installed with the ADS SDK and other essential Python packages for data science workflows.

Explanation

Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).

Large Compute clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront provisioning.

The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service supports the Network Lock Manager (NLM) protocol for file locking functionality.

Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection. Data is protected with erasure encoding.

The File Storage service uses the "eventual overwrite" method of data eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used space, and eradicates all residual files.

Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:

The primary use case for using Web Application Firewall (WAF) in OCI is to filter malicious web traffic and protect internet-facing and internal applications from attacks. WAF is a cloud-based, PCI-compliant, global web application firewall service that monitors and controls access to web applications based on predefined rules and threat intelligence. WAF can block common web application attacks such as cross-site scripting (XSS), SQL injection, remote file inclusion, etc., as well as bot traffic, geographic restrictions, rate limiting, etc. WAF can protect any internet-facing endpoint or internal application by attaching WAF policies to enforcement points such as load balancers or web application domain names10
