Customer Concentration and Diversification

While Arista's growth is impressive, it comes with some risks. The company is heavily dependent on a small number of large customers, particularly in the cloud and AI sectors. Microsoft and Meta Platforms alone accounted for approximately 39% of Arista's total revenue in fiscal 2023 3
