PT Semen Indonesia (Persero) Tbk, or Semen Indonesia \u2014 formerly known as PT Semen Gresik (Persero) Tbk \u2014 is a well-known cement company in Indonesia\u2019s building materials industry. The company began operations in 1957 and has since grown into one of the largest cement producers in Southeast Asia.\nSemen Indonesia is headquartered in Gresik, East Java and plans to open a new office in Jakarta. Its annual sales revenue generates approximately US$2.3 billion (IDR 33.4 trillion). Semen Indonesia\u2019s vision is to become the world\u2019s largest cement company.\nChallenges\nIn the face of such fast business growth, Semen Indonesia expects to improve automation and digitalization with an optimal ICT infrastructure. As such, the existing ICT infrastructure needed to be renovated. ICT infrastructure transformation must avoid service interruptions to prevent financial losses, as it is estimated that if services are interrupted for half an hour, financial losses will reach US$100,000 (IDR 1.45 billion). Devices from multiple vendors coexist on the live network, and the growing diversity of services complicates network Operations and Maintenance (O&M) and interoperability. The upgraded ICT infrastructure must reduce network complexity. In addition, this new ICT infrastructure must be future-proof and meet service development needs over the next three to five years.\nPreviously, Semen Indonesia\u2019s services used a single data center to\u00a0operate. If a data center outage lasted more than two hours, business transactions would be hindered, manufacturing and distribution would be delayed, and IT infrastructure and systems would be damaged.\nSolution\nTo improve ICT services for business continuity, Semen Indonesia initiated an active-active data center project. The new data center infrastructure must use the latest technologies and ensure data security, reliability, and continuity.\nSemen Indonesia\u2019s active-active data center must feature:\n\nActive-active data center infrastructure between DC1 and DC2 for Tier-1 applications, and active-standby between DC1 and DC2 for Tier-2 applications\nSoftware-Defined Networking (SDN)-based automation\nSmooth Virtual Machine (VM) migration within a single data center and across multiple data centers\nStrong network security protection with Intrusion Prevention System (IPS), anti-virus capabilities, bandwidth management, firewall security policies, and security group features\nNetwork load-balancing\nFuture-proof support for software and hardware requirements for a minimum of the next five years\n\nAfter assessment of Semen Indonesia\u2019s situation and requirements, Huawei proposed a CloudFabric Active-Active Data Center Solution that uses SDN technology to avoid single-site data center failures and ensure continuity and availability of key services.\nHuawei\u2019s expert team assisted Semen Indonesia to sort their services and redefine their network using Huawei\u2019s CE-series switches that feature a spine-leaf architecture and SDN technology, Next-Generation Firewalls (NGFWs), RH-series servers, as well as storage. All operate on a single cloud platform.\nHuawei\u2019s holistic solution interoperates with legacy products and solutions, minimizes project costs, and reduces the Total Cost of Ownership (TCO).\nHuawei also provided a complete data center migration solution to ensure smooth service migration and avoid losses caused by service interruptions.\n Huawei\nHuawei\u2019s SDN-capable solution deploys Virtual Extensible Local Area Network (VXLAN) to set up active-active data centers and ensure smooth VM migration between data centers.\nThe new data center network has the following functional areas: Border Zone, Core Zone, Product Zone, and Management Zone.\n\nBorder Zone: Provides Internet access, third-party bank connectivity, and branch office connectivity.\nCore Zone: Provides routing and interconnection between other zones, as well as between data centers.\nProduct Zone: Defines the service resources and network resources using SDN technology\nManagement Zone: Manages all devices via out-of-band interfaces.\n\n Huawei\nOverall Network Topology\nHuawei\u2019s CloudFabric Solution helped Semen Indonesia build an SDN-based data center network. Through automated network configuration and added L4-to-L7 value-added services (such as firewalls and load-balancers) for on-demand application networks, this new network implemented Network-as-a-Service (NaaS) for substantial improvement of service deployment efficiency while network O&M is simplified.\nA highly reliable Disaster Recovery (DR) and backup solution from Huawei greatly improves the availability and security of Semen Indonesia\u2019s core network systems. In addition, the migration from the old to new systems with efficient interoperability is interruption-free. Huawei\u2019s solution ensures smooth evolution and will support the service needs of Semen Indonesia over the next five years.\nBenefits\nThe Huawei solution benefits Semen Indonesia in a number of tangible ways. For example:\n\nThe highly available data center delivers more stable and reliable services, to eliminate service interruption risk.\nSDN support ensures the innovativeness and scalability of IT systems.\nLayered service DR design, in-depth optimization on IT systems, and more efficient O&M maximizes Return On Investment (ROI).
