Optimizing AWS Snapshot Costs: Best Practices for Cost Optimization
- Regularly reviewing and deleting old EBS snapshots helps avoid unnecessary storage costs.
- Automating AWS snapshot management with Amazon Data Lifecycle Manager saves time and reduces operational complexity.
- Analyzing EBS usage helps identify cost optimization opportunities, including resizing volumes and provisioning IOPS.
- Proper storage tiering with S3 helps reduce costs by using the appropriate storage class based on access patterns.
- Data lifecycle policies help manage storage efficiently by archiving or deleting unused data and compressing data before storage.
- Monitoring storage metrics in S3 or EBS can help optimize resource utilization and identify cost-saving opportunities.
- Choosing the right EBS volume type, such as General-purpose SSDs (gp2, gp3) or Provisioned IOPS SSD (io1, io2), can improve performance.
- EBS-Optimized Instances can provide dedicated bandwidth between EC2 instances and EBS volumes, leading to improved performance.
- Moving older EBS snapshots to cheaper S3 storage and utilizing S3 storage classes can further optimize costs.
- Implementing lifecycle policies and monitoring storage metrics with tools such as Amazon S3 Storage Lens is crucial for optimizing resource utilization and cost control.

How to use GitHub Personal Access Tokens Securely
- GitHub personal access tokens are a better option than passwords, especially for working with GitHub through APIs and command-line operations.
- Fine-grained personal access tokens are recommended as they provide detailed permission and access control to only the specific resources required, reducing security risks.
- Classic tokens provide wider access and lack granularity, but are still necessary for many established workflows.
- Tokens should be deleted when no longer needed to avoid exposing programs to any risks.
- Token caching increases efficiency by remembering the token, and these credentials can be cached for a set duration.
- Best practices include only creating tokens with necessary privileges, using fine-grained tokens wherever possible, and embracing other authentication methods to secure workflows.
- Developers can minimize risks with mismanaged tokens by regularly cleaning up and revoking old or unused tokens.
- Monitoring tools like CICube provide detailed insights to optimize CI/CD pipelines.
- Overall, GitHub personal access tokens are powerful and following secure management practices can ensure a safe development environment.

9 Ways to Handle Secrets Management for Multi-Cloud Setups: Rotation, Auditing, and Access Control
- Gartner suggests that new security threats are among the biggest pain points for CIOs across businesses.
- Secrets management is an essential part of cybersecurity strategy for multi-cloud infrastructure.
- Managing secrets requires ways to protect them from breaches and unauthorized access and monitor their usage.
- Three main methods—rotation, auditing, and access control—can ascertain such proactiveness and vigilance in secrets management.
- Nine ways to implement these techniques are discussed with their contrast for different cloud vendors, namely AWS, Azure Cloud, and GCP Cloud.
- Secret rotation is the first line of defense where the secrets are consistently rotated or updated to minimize, if not eliminate, any breaches.
- Secret auditing allows security teams and cloud management experts to track when API tokens, encryption keys, and other such secrets were accessed and used for any services.
- Access control is critical for multi-cloud-based secrets management as it helps implement the principle of least privilege on the secrets.
- Multi-cloud infrastructure is one of the most sensible choices for businesses when dealing with cloud computing.
- Secrets management is necessary to maximize multi-cloud's potential while ensuring top-notch security and compliance.

PL/SQL Developer Interview Questions with 3 years of experience
- PL/SQL is Oracle's procedural extension to SQL while SQL is a language for querying databases and performing operations.
- Cursors in PL/SQL are pointers to a result set, allowing row-by-row processing and can be explicit or implicit.
- A trigger is a stored procedure that executes automatically in response to certain events on a table
- Procedures perform actions and don’t return values directly, while Functions must return a single value.
- Predefined exceptions like NO_DATA_FOUND, TOO_MANY_ROWS, and ZERO_DIVIDE help handle specific issues that may arise during execution.
- The three main types of PL/SQL Collections are Associative Arrays, Nested Tables, and VARRAYs.
- Optimizing PL/SQL code involves several practices like using bulk collect and forall for bulk operations.
- The %TYPE and %ROWTYPE attributes are used to declare variables that automatically adopt the datatype of a table column or the entire row structure of a table.
- A package is a collection of PL/SQL objects like procedures, functions, variables, and types grouped together.
- BULK COLLECT fetches multiple rows at once into a collection, while FORALL allows performing DML operations on collections, both reducing context switching between PL/SQL and SQL.
