Image
  Automating VLAN Creation on Cisco Devices with Ansible Ansible is a powerful automation tool that simplifies network management tasks, including creating VLANs on Cisco devices. For beginners, this guide will walk you through automating VLAN creation step-by-step, from setting up Ansible to deploying VLAN configurations. What is a VLAN? A VLAN (Virtual Local Area Network) is a logical group of devices within a network that can communicate as if they were on the same physical network, regardless of their physical location. VLANs improve network efficiency and security by segmenting traffic. Why Use Ansible for VLAN Automation? Consistency: Avoid manual configuration errors. Efficiency: Configure multiple devices in seconds. Scalability: Manage large-scale networks easily. Flexibility: Supports various Cisco devices and integrates with other tools. Prerequisites Cisco Device Configuration: Ensure your Cisco devices support SSH and are configured to allow Ans...

 How to Become a Database Engineer: A Comprehensive Guide

Database engineers play a critical role in designing, managing, and optimizing data storage systems that power modern applications and services. If you’re interested in pursuing a career in database engineering, here’s a step-by-step guide to help you get started and excel in this field.

1. Understand the Role of a Database Engineer

Before embarking on this career path, it’s essential to understand what database engineers do. Their responsibilities include:

  • Designing and creating databases.
  • Managing database performance and scalability.
  • Implementing security measures to protect data.
  • Developing and optimizing SQL queries.
  • Collaborating with software developers and system administrators.

Database engineers often work with relational databases like MySQL, PostgreSQL, and Oracle, as well as NoSQL databases like MongoDB and Cassandra.

2. Develop a Strong Educational Foundation

While it’s possible to become a database engineer without formal education, most employers prefer candidates with a degree in a relevant field, such as:

  • Computer Science
  • Information Technology
  • Software Engineering

During your studies, focus on courses that cover database management systems (DBMS), programming, data structures, and algorithms.

3. Learn Key Database Technologies

Familiarize yourself with essential database technologies and tools, including:

  • SQL (Structured Query Language): The backbone of relational databases.
  • Database Management Systems (DBMS): Learn systems like MySQL, PostgreSQL, Oracle, and SQL Server.
  • NoSQL Databases: Explore MongoDB, Couchbase, or DynamoDB for handling unstructured data.
  • Cloud Database Services: Gain knowledge of AWS RDS, Google Cloud SQL, or Azure Database.

4. Master a Programming Language

Database engineers often work closely with software developers. Proficiency in programming languages can enhance your ability to integrate databases into applications. Popular languages include:

  • Python
  • Java
  • C#
  • PHP

5. Gain Hands-On Experience

Practical experience is crucial for developing your skills. You can:

  • Build personal projects that involve database design and management.
  • Contribute to open-source projects.
  • Participate in internships to gain real-world exposure.

6. Understand Database Design Principles

Learn how to design efficient and normalized databases. Key principles include:

  • Normalization: Reducing data redundancy.
  • Indexing: Improving query performance.
  • Data Modeling: Creating logical and physical models of your database.

7. Develop Problem-Solving Skills

Database engineers often troubleshoot performance issues and optimize queries. Practice solving problems related to:

  • Query optimization.
  • Deadlock resolution.
  • Data migration and replication.

8. Pursue Certifications

Certifications can validate your expertise and enhance your resume. Popular certifications include:

  • Microsoft Certified: Azure Database Administrator Associate.
  • Oracle Certified Professional (OCP) MySQL Database Administrator.
  • AWS Certified Database - Specialty.


9. Stay Updated with Industry Trends

The database field evolves rapidly with new technologies and methodologies. Stay current by:

  • Following industry blogs and forums.
  • Attending webinars and conferences.
  • Learning about emerging technologies like database automation and AI-driven database optimization.

10. Network and Build a Portfolio

Networking can open doors to job opportunities. Join professional groups, attend meetups, and connect with other database professionals on platforms like LinkedIn. Additionally, maintain a portfolio of projects to showcase your skills to potential employers.

11. Apply for Jobs and Grow Your Career

When you’re ready, apply for entry-level positions such as Database Administrator or Junior Database Engineer. As you gain experience, you can advance to roles like Senior Database Engineer, Database Architect, or Data Engineer.

Conclusion

Becoming a database engineer requires a mix of technical skills, hands-on experience, and continuous learning. By following these steps, you can build a strong foundation and position yourself for success in this rewarding field. Whether you’re managing massive data warehouses or optimizing high-traffic applications, a career in database engineering offers endless opportunities for growth and innovation.

Network Access Control NAC It's something that controls access to the network. And at its simplest level, this is what NAC does.  But if that's all that it was, then it wouldn't be fundamentally different from a network authentication and authorization server. Traditional authentication to the network follows the IEEE 802.1X standard that provided an authentication method to devices wishing to join a Local Area Network (LAN) or wireless LAN. 802.1X Wireless/Wired Authentication The mechanism was a port-based network access control which used agents, the software running on client devices that provide credentials to the authenticator to control access to the network. Another means to control access to a public network such as one serving a coffee shop or in a hotel, is a captive portal. If you've ever connected to a network in an airport, hotel, or coffee shop, you might recall interacting with a web page, sometimes agreeing t...

1- Definition   DMVPN is a technology that's used in secure networks exchanging data between them without needing to redirect traffic through a  headquarter  server  or router . Dynamic Multipoint VPN ( DMVPN ) is a Cisco IOS Software solution for building reliable IPsec Virtual Private Networks (VPN). DMVPN basically is a centralized architecture that provides easier management and implementation for deployments that need very specific access controls, authorizations and restrictions for diverse branches, users, applications and partners. DMVPN + IPSEC 2- Benefits DMVPN provides the ability to create dynamic VPNs without configuring static tunnels between remote peers, including Internet Protocol (IP), IPSEC and Key Management Protocol (ISAKMP peers).   DMVPN is designed  to make HUB-AND-SPOKE   topology  by statically configuring the hub IP address on the spokes, no other changes are needed ...

Issues with CISCO WIRELESS Controller (And resolution) | IT NETWORKS

On Cisco Wireless controller 5520, The Access POINTS try to join the Controller by bringing up a connection through the CAPWAP Tunnel, you can see these attempts through the AP log itself. The problem is that the DHCP server when trying to serve IP Addresses it shows the error BAD_ADDRESS in front of each IP assigned. So I Took a single access point, started debugging it, after that, I noticed that the CAPWAP connection was empty of errors BUT!! it was trying to resolve this name  CISCO-CAPWAP-CONTROLLER This resolution is made with DNS protocol, of course, I honestly wasn't so sure of what I was doing, so I added a new entry in my DNS server and it's corresponding IP was the Controller's after that magically all the Access Points where UP and showed UP on my controller. The controller I'm working with is the CISCO WIRELESS CONTROLLER 5520 Model:  AIR-CT5520-K9 Software Version:  8.3.150.0 Image of the controller Learn...
