Company Snapshot

What Arista Does

Arista manufactures high-performance Ethernet switches exclusively designed for cloud data centres and financial markets. Their flagship products include the 7000 series switches (DCS-7048, DCS-7050 series) that run EOS (Extensible Operating System), a Linux-based network OS optimised for cloud scale. Unlike Cisco and Juniper, Arista does not manufacture routers or security appliances; the company is purely focused on data centre and financial network switching.

Arista owns approximately 30% of the cloud hyperscaler switching market. Competitors include Juniper, Cisco, and Broadcom for data centre environments, but Arista's focus on cloud-native architecture and its adoption by AWS, Google Cloud, Meta, and Microsoft gives it market leadership in hyperscaler deployments. The certification program is designed for cloud network engineers and data centre architects.

Why Arista Matters in 2026

Arista is the dominant Ethernet switch vendor for cloud hyperscalers globally. LinkedIn shows 3,200+ open Arista/ACE job postings, primarily at cloud infrastructure companies (AWS, Google Cloud, Meta, Microsoft, Apple). ACE-L2 and ACE-L3 certifications are particularly valuable for cloud network engineers and data centre architects.

Arista's adoption by hyperscalers ensures that demand for ACE certifications will continue growing as cloud infrastructure expands. The certification ecosystem is smaller than Cisco or Juniper but is exceptionally healthy within the cloud ecosystem. Arista maintains close relationships with major cloud providers and invests in training platforms. For cloud network engineers, ACE certifications complement AWS, GCP, and Azure networking certifications exceptionally well.

Job Market Data

Global demand

Common job titles requiring Arista skills

South Africa Presence

Direct presence

Arista has limited direct presence in South Africa. The company operates primarily through a partner network, with Logicalis and other regional system integrators providing support. Most Arista deployments in SA are remote-managed by global cloud infrastructure teams.

SA job market

South African cloud infrastructure teams working for global hyperscalers (AWS, Google Cloud, Microsoft) may require Arista expertise, but remote work dominates. Domestic SA organisations have minimal Arista presence; Cisco and Juniper remain standard in enterprise data centres. ACE certifications are most valuable for SA engineers working for global cloud companies or migrating to cloud-focused roles.

Median salary for ACE-certified Cloud Network Engineers is R101,200/month (approximately $5,500 USD) globally, significantly higher than entry-level networking certifications due to cloud infrastructure premium.
