• Documentation, samples, and guides: Hazelcast offers helpful documentation, white papers, webinars, videos and more on a variety of topics to help users maximize their Hazelcast investment.

Hazelcast security measures:

1. Encryption: Data security measures involve encrypting data to transform it into an unreadable format, ensuring that only authorized users can access it. Encryption keys scramble data, providing a secure way to protect sensitive information.

2. Firewall and Virus Protection: Implementing firewalls and antivirus protection is crucial to safeguarding networks and systems from cyber threats like Trojans, viruses, worms, and malware. Firewalls control internet traffic to prevent unauthorized access and protect against cyberattacks.

3. Regular Updates: Keeping systems and software up-to-date with regular patches and updates is essential for maintaining data security. Software developers continuously work to close security gaps, and installing updates promptly enhances data security.

4. User Access Control: Defining user roles and limiting access rights within a company helps reduce the risk of improper handling of data. Access to sensitive information should be restricted to employees who require it for their tasks, minimizing the potential for data breaches.

5. Data Encryption at Rest and in Transit: Encrypting data during transfer and storage is a critical security measure. Data should be encrypted when transmitted between locations and stored on servers to prevent unauthorized access and ensure data confidentiality.

6. Secure Data Exchange: Using secure platforms for data exchange, such as shared clouds, instead of email, enhances data security. Discussing data security measures openly with business partners and ensuring secure data exchange methods are in place are essential steps to protect sensitive information.

7. Employee Training: Educating employees about data security and raising awareness about the importance of following data security protocols is crucial. Regular training sessions can help employees understand the risks associated with data breaches and the impact of non-compliance with data security requirements.

8. Data Backup and Recovery: Scheduling regular backups to external hard drives or cloud storage ensures that data is securely stored and can be recovered in the event of data loss or system failures. Backing up data helps maintain data integrity and availability.

• Hazelcast Jet releases new versions every 3-4 months with bug fixes and new features. Upgrading to a new version is a simple process of replacing the Jet library.

• The latest version of Hazelcast Jet is 4.5.4, released in 2024. Previous versions like 4.4, 4.3.1, 4.2, and 4.1.1 were released in the months and years prior.

• Hazelcast provides release notes for each new version of Jet, detailing the new features, enhancements, and bug fixes. The release notes help users understand what has changed and plan their upgrades accordingly.

1. Data Ownership: Hazelcast ensures that data ownership is maintained within the cluster. Each member in the cluster is aware of the data partitions it owns and is responsible for. This distributed ownership model ensures that data is resilient to member failures, as backups are distributed across the cluster.

2. Data Portability: Hazelcast Jet supports a wide variety of data sources and sinks, enabling seamless data import and export. It integrates with systems like Hadoop, S3, Apache Kafka, Elasticsearch, JDBC, and JMS, allowing users to move data in and out of the Hazelcast cluster efficiently. This flexibility ensures that data can be ported across different systems and environments as needed.

3. AP and CP Guarantees: Hazelcast offers both AP (Availability and Partition tolerance) and CP (Consistency and Partition tolerance) data structures, providing different levels of consistency and availability guarantees. This allows users to choose the appropriate data structure based on their specific requirements for data consistency and portability.

4. Security and Compliance: Hazelcast provides security features to protect data, including securing Jet engine jobs and ensuring that data access is controlled and monitored. This is crucial for maintaining data ownership and ensuring compliance with data protection regulations.

1. Automatic Scaling: By default, Hazelcast Jet jobs scale up or down automatically when you add or remove cluster nodes. This allows easily adapting to change processing requirements.

2. Restarting Jobs: When scaling, Hazelcast Jet must restart jobs to rescale them. The jobs will automatically restart from the latest known snapshot, ensuring no data loss.

3. Kubernetes Support: In Kubernetes environments, you can use the standard kubectl scale command to change the Hazelcast Jet cluster size. This makes scaling straightforward in containerized deployments.

4. Graceful Shutdown: When scaling down, you can configure Hazelcast Jet to use graceful shutdown, which triggers partition migration before terminating pods. This ensures data safety when rapidly scaling down the cluster.

5. Fault Tolerance: Hazelcast Jet provides fault tolerance through snapshotting, allowing jobs to resume from the latest snapshot when nodes are added or removed. This enables scaling without data loss.

Contract Renewal:

1. Term of Agreement: The initial term of the agreement begins on the effective date and lasts until the expiration date specified in the order form.
