Explore the fundamental principles of network design, apply them to planning data centers, and learn to plan resources, capacity, and integration of servers, switches, security, and management services.
This Lecture covers Basic Principals of Designing Data Center.
There is always questions from Where Do We Start ? Answer is there in this Video...
Its critical aspect for Doing Resource and Capacity Planning for preparing BoQ of Data Center, lets learn how to do Resource Planning properly.
After Finalizing Resources, lets understand how to select Server and Switches for Data Center Deployment.
Extract resource requirements from applications to select servers, switches, and service layers, management, and orchestrator layers; map traffic flow, plan physical and logical connectivity, and integrate with monitoring.
WAN Layer Covers WAN Router, Security Stack and then it connected to Switch Layer, lets discuss the same in detail...
Position security devices as the data center's first line of defense, from ddos protection at entry to firewall, ips, ssl decryption, and load balancing for encrypted traffic.
configure DNS to resolve FQDN to legitimate application IP and redirect users to approved apps, then enforce URL filtering against a database to block unauthorized web traffic in the DMZ.
Position security components in the data center DMZ by deploying a firewall and an ELB between web and app, using DNS and FQDN for resolution and port-based policies.
Position secure entry points such as VPN, jump post, and VDI to grant authorized users controlled access to data center equipment, with AAA policies defining access scope and activity monitoring.
Before we understand what and how to integrate with management services, its necessary to know what activities performed by NOC / Operation Team.
Lets discuss in detail how Server, Switches, WAN, Security Stack gets integrated with Management Services Component.
Its critical to protect all equipment from accessing from unauthorized users and only authorized users supposed to have desired access. lets discuss how to enable the same.
Explain how management services components connect to data center equipment via out-of-band and in-band networks, using uplinks of 1g to 40g and OB aggregation to handle continuous elephant flow traffic.
Lets understand sub component of Server and use of each.
Explore data center storage, including web content, business and email data, SQL/NoSQL databases, and analytics, with SSD vs HDD, DAS, NAS, SAN, and cloud options.
Compare bare metal and virtualization, explain how hypervisor creates and allocates VM resources with guest operating systems, and show how clustering, redundancy, and switching enable scalable, high-performance data center compute.
Trace the shift from traditional three-layer data centers to leaf-and-spine with vxlan evpn, underlay/overlay architectures, anycast gateways, and controller-based management.
Explore how vxlan evpn extends layer 2 across geographically separated sites, keeping vlan 10 and vlan 11 in the same subnet over a single l3 network, enabling active-active data centers.
Lets understand how all equipment are physically to be connected with each other.
After physically connect, lets discuss how these equipment logically integrated and packet flow through it.
Its important to document everything to have single source of truth. There are various document need to have it during designing, deployment and handover Data Center to NOC-Operation Team.
Lets conclude this course with summary of all discussion and next step.
This course is for any person who working or will be working on data center design, deployment or operate. This also help for the one who are planning to interview or approaching any data center Job.
This course start from basic principal of designing any network and then progress with where to start journey of designing data center, selection of various component like Server, Storage, Switch Layer, WAN, Security, Management Services, Out of Band / Inband Management network etc.
Discussed on each component (Server, Storage, Switch Layer, WAN, Security, Management Services, Out of Band / Inband Management network etc) of data center in details, how to integrate all these component with each other using physical and logical connectivity.
Witch Protocol to be run between these component, where to define Gateway, how and where to advertise prefixes for both North to South and East to West Communication.
This course further progress with packet flow from end user to Application via Security, Switches and Server layer. Discussed in details about how all data center component to be integrated with management services like EMS, NMS (using SNMP, API), Syslog, Backup Server, AAA, PIM etc. for day to day monitoring, management and operate.
In Summary, this course cover in details of every aspect which require to design data center using various design principal (like availability, security, redundancy, scalability, flexibility etc.)
This course end with covering various documentation which need to prepare and what all preparation to be done before handing over data center to NOC / Operation Team for day to day management and operate.
In last course concluded with references courses which will help for further enhancing skill for engineer / professional working on data center environment.
