Enterprise IT Glossary
Clear, concise definitions of the key enterprise IT terms, technologies, and acronyms used by IT professionals and decision-makers.
A
AIOps
AIOps (Artificial Intelligence for IT Operations) applies machine learning and big data analytics to automate and enhance IT operations — including event correlation, anomaly detection, and incident resolution — reducing MTTR and operational costs.
B
Business Continuity Plan (BCP)
A Business Continuity Plan is a documented strategy outlining how an organisation will maintain essential operations during and after a disaster or disruption, covering IT recovery, communication protocols, and alternate operational procedures.
C
CCTV & Physical Security
Enterprise CCTV and physical security systems provide perimeter surveillance, access control, and intrusion detection using IP cameras, biometric readers, and video management systems from vendors like Bosch, Axis, and Honeywell.
Cloud Adoption
Cloud adoption is the migration of enterprise workloads, applications, and data from on-premise infrastructure to public, private, or hybrid cloud platforms such as Microsoft Azure, AWS, or Google Cloud — enabling scalability, cost optimisation, and agility.
Colocation (Colo)
Colocation involves housing enterprise servers and networking equipment in a third-party data centre facility. Enterprises benefit from tier-rated power, cooling, and connectivity without owning the facility — partnered through providers like Yotta, STT, and Equinix.
CrowdStrike Falcon
CrowdStrike Falcon is a cloud-native endpoint detection and response (EDR) platform that uses AI to detect, prevent, and respond to cyber threats in real-time across endpoints, workloads, and identities.
D
Dedicated Internet Access (DIA)
Dedicated Internet Access provides a fixed, guaranteed bandwidth connection for businesses — unlike shared broadband. DIA ensures consistent speeds and SLA-backed uptime, critical for enterprise cloud and VoIP applications.
DRaaS (Disaster Recovery as a Service)
DRaaS replicates and hosts physical or virtual servers in a cloud environment to recover IT systems after a disaster. It provides RPO and RTO guarantees, reducing downtime and data loss for mission-critical systems.
E
EDR (Endpoint Detection and Response)
EDR is a cybersecurity technology that continuously monitors endpoint devices (laptops, servers) to detect and respond to threats. EDR solutions like CrowdStrike and Trend Micro provide real-time threat hunting and automated remediation.
F
Firewall (NGFW)
A Next-Generation Firewall (NGFW) inspects network traffic at the application layer, providing deep packet inspection, intrusion prevention, SSL/TLS inspection, and application-aware policy enforcement — deployed by vendors like Fortinet and Palo Alto Networks.
G
Google Workspace
Google Workspace is a cloud-based productivity suite including Gmail, Google Drive, Docs, Sheets, Meet, and Chat — enabling enterprise collaboration. Layots Technologies is an authorised Google Workspace deployment partner.
H
Hybrid Cloud
Hybrid Cloud combines private on-premise infrastructure with public cloud services, connected via secure networking. Enterprises use hybrid cloud to run sensitive workloads on-premise while leveraging cloud scalability for dynamic or non-sensitive workloads.
Hyperscale Cloud
Hyperscale cloud refers to the ability of cloud infrastructure to scale massively on demand, provided by hyperscalers like AWS, Microsoft Azure, and Google Cloud. These platforms offer virtually unlimited compute, storage, and network resources.
I
ITSM (IT Service Management)
ITSM is the practice of designing, delivering, managing, and improving IT services. It uses frameworks like ITIL to align IT with business objectives, typically implemented via ticketing platforms like ServiceNow or Freshservice.
M
MPLS (Multiprotocol Label Switching)
MPLS is a high-performance WAN protocol that routes traffic based on short path labels rather than IP addresses. MPLS provides guaranteed bandwidth, low latency, and QoS — commonly used for enterprise branch connectivity.
Microsoft 365 (M365)
Microsoft 365 is a cloud-based productivity suite including Outlook, Teams, SharePoint, OneDrive, and Office apps. It provides enterprise collaboration, communication, and compliance tools with built-in Microsoft Defender security.
Microsoft Azure
Microsoft Azure is a leading public cloud platform offering 200+ services including virtual machines, databases, AI/ML, DevOps, and security. Layots Technologies is an authorised Microsoft Azure solutions partner for enterprises in India.
N
NOC (Network Operations Centre)
A Network Operations Centre is a centralised facility from which IT engineers monitor, manage, and maintain network infrastructure 24/7. Layots operates a dedicated NOC providing real-time visibility and rapid incident response for enterprise clients.
P
P2P (Point-to-Point) Connectivity
Point-to-Point connectivity provides a dedicated private leased line between two locations — offering guaranteed bandwidth, low latency, and high security. Ideal for enterprise data centre interconnects and branch-to-HQ connectivity.
Patch Management
Patch management is the process of identifying, downloading, testing, and deploying software updates (patches) to IT systems to fix security vulnerabilities and improve performance. Timely patching is critical for preventing ransomware and exploits.
R
RTO / RPO
Recovery Time Objective (RTO) is the maximum acceptable downtime after a disaster. Recovery Point Objective (RPO) is the maximum acceptable data loss measured in time. Both are key parameters for disaster recovery planning and SLA definition.
S
SD-WAN (Software-Defined WAN)
SD-WAN uses software to intelligently route traffic across multiple WAN links (MPLS, broadband, LTE) based on application needs. It reduces WAN costs by 40–60%, improves cloud application performance, and centralises network management.
SIEM (Security Information and Event Management)
SIEM collects and correlates security event data from across IT infrastructure to detect threats, generate alerts, and support compliance reporting. Modern SIEMs use AI to reduce false positives and accelerate threat detection.
SOC (Security Operations Centre)
A SOC is a team of cybersecurity analysts who continuously monitor, detect, and respond to security threats across an organisation's IT environment. Layots provides 24/7 managed SOC services for enterprise clients.
SSL/TLS Certificate
An SSL/TLS certificate encrypts data transmitted between a user's browser and a web server, securing sensitive information. Enterprises require TLS certificates for all web applications, APIs, and internal services to ensure data integrity and compliance.
U
UPS & Power Management
Uninterruptible Power Supply (UPS) systems provide emergency power backup during grid failures. Enterprise-grade UPS from Schneider Electric and Vertiv ensure continuous operation of servers, network equipment, and data centres.
V
VAPT (Vulnerability Assessment & Penetration Testing)
VAPT is a security testing methodology combining automated scanning (VA) with manual ethical hacking (PT) to identify exploitable vulnerabilities. Layots conducts VAPT audits across network, application, and endpoint layers.
VMware Virtualisation
VMware virtualisation technology allows multiple virtual machines to run on a single physical server, maximising hardware utilisation, simplifying management, and enabling rapid workload provisioning in enterprise data centres.
VPN (Virtual Private Network)
A VPN creates an encrypted tunnel over the internet, allowing remote users or branch offices to securely access corporate resources. Enterprise VPNs are deployed using solutions from Cisco, Fortinet, and Palo Alto Networks.
Z
Zero-Trust Security
Zero-Trust is a security framework based on the principle "never trust, always verify." Every user, device, and application must be continuously authenticated and authorised before accessing any resource — regardless of network location.
ZTNA (Zero-Trust Network Access)
ZTNA provides secure, identity-based access to specific applications rather than entire network segments. Unlike VPNs, ZTNA applies least-privilege access policies continuously, reducing attack surface and lateral movement risk.
