Technical Skills vs Soft Skills: Finding the Right Balance for Career Success

Employers increasingly value both technical and soft skills in professionals to meet evolving job demands.
Technical skills (hard skills) are teachable abilities like programming and data analysis, acquired through education or training.
Soft skills (interpersonal traits) such as communication and adaptability are learned through experience and feedback.
Technical skills are domain-specific, while soft skills are transferable across roles and industries.
Learning technical skills involves structured courses, while soft skills develop informally and are measured subjectively.
Soft skills like leadership and problem-solving remain relevant even as technology evolves and technical skills become outdated.
Examples of technical skills include programming languages, data analysis, and cybersecurity, while soft skills include communication, leadership, and adaptability.
In the future of work, both technical skills and soft skills will be crucial as AI and automation redefine job roles and remote work models become prevalent.
Leading companies like Google and Salesforce emphasize the importance of a balance between technical expertise and soft skills for success.
To build a future-proof skill set, professionals should invest in continuous learning, practice communication, seek feedback, work cross-functionally, and stay agile.
A combination of technical proficiency and strong soft skills will be essential for professionals to navigate complex challenges and drive innovation in the evolving workplace.

Strengthening S2S Security: How JioHotstar Secures Its Service Ecosystems

As organisations shift towards distributed systems and micro-services, vulnerabilities in service-to-service (S2S) communication can have serious consequences, with a majority reporting susceptibility to insider attacks.
Implementing static tokens initially for S2S security, the system later evolved to dynamic tokens with Time-to-Live (TTL) for better security and reduced exposure.
The hybrid token model was introduced to ensure security and resiliency by using dynamic tokens predominantly and static tokens as backups during system failures.
To prevent misuse of static tokens during normal operations, an enhanced hybrid token model with a heartbeat mechanism was developed.
Addressing inconsistent heartbeat issues in the system, a mechanism was designed with periodic health probes and graceful transition periods for operational continuity.
Considerations for partition tolerance and network issues were taken into account, with the flexibility to adjust token usage during extreme conditions.
The evolution of JioHotstar's token management mechanism in their IAuth platform showcases their dedication to enhancing security, resiliency, and operational continuity in S2S communication.
The article highlights the journey from static tokens to dynamic tokens and the subsequent development of a sophisticated hybrid model to fortify the service ecosystem against potential attacks.
Constant innovation and deep understanding of failure points are emphasized for securing distributed systems, with the IAuth solution being flexible and robust in safeguarding interactions across complex service landscapes.
The importance of adapting defenses against evolving threats to S2S communications is underscored, with a call for discussions on effective strategies for protecting critical services from internal vulnerabilities.
