NETWORKING Locate anywhere Fridström claims that fibre optics now make it possible to build and locate a data centre anywhere. In my view you can now create global access to data centres to mitigate disaster recovery (DR) geographical constraints. In doing so it becomes possible to move computing closer to the consumer, and perhaps even closer to the edge. However, the speed of light is finite (at the moment) and that can cause issues, making it harder to move volumes of data between data centres. Network latency and packet loss remain issues that can diminish data centre performance. Many organisations fail to factor in the effect of the speed of light when designing geographically dispersed solutions. For high-speed trading platform data, the distance between data centres affects the time between transactions. However, for low-speed transactional data composed of a small number data packets a few milliseconds of delay isn’t critical. Data accelerate When transferring large volumes of data such as workloads or backup as a service transactions latency and packet lo 72276fRF&VvWBW"R6( BRFR7VVBbƖv@vf7FW"6RW7BfBFW"v&VBFR&&VFF66VW&F6WF27V62%G&6BF&VvFPW6Rb&VƗ6FB6fRG&F2VffV7B&W7F&rFFF&VvWBVƖRtF֗6F2FW66W&֗BV7'FVBfW2F&RG&6֗GFVB6V7W&Vǒ@7VVB&WGvVVFF6VG&W2FB&R6FVBWG6FRbFV v6&6W2bF7'WFtF֗6F6WF2gFV6( BFVvFV7'FVBFF&WV&rFRFFFgFV&R6V@VV7'FVBFV7W&RFB7VVFW"FFG&6֗766&R6WfVB&VfW"vRtF֗6FB4BtfVF'2gFV6FWFVvFV7FWgFVF( @7Vff6VFǒRFffW&V6RFWGv&W&f&6R@vW"t7VVG2FB&Rrf&R6G&7BFF66VW&F6WF2W6R6RV&rF֗FvFRFPVffV7G2bFFBWGv&FV7vFFVFR76&ƗGbfrF֗6VBFF6VG&W2BF67FW"&V6fW'6FW2FffW&VB'G2bFRv&BvFFR7BbFV7&VpV6&VGV6VB&V6W2&RfV6&RWr'GVFW0vW"67G27&VFR'GVFW2f"FW6vrvr@W&FrFVB6VB6WFr&W6W&6W2FVVBvF6W'f6R&fFW'2rF涖rv&ǒf'&RV2WvR&vRb'GVFW2f"&v6F2&F&vR@67F&VƖWfRFBV&Ɩ22FRǒ6VBFVf&RvWfW"FR&vW"&v6F2vFf'GVƗ6VBF7G&'WFVBFF6VG&W2&RƖVBvFv7VVBf'&R6FW67&VFRFV"v6VBg&7G'V7GW&Rf"6V@7F&vRB6VB6WFrF2WfW'FVW72vVfRFPFV&FR&WBvWFW"N( 26VW"f"FVFWG6W&6RFF&B'GFF6VG&W2"vWFW"N( 26VW"FfRFV vFF6VG&W26vFFR6vrFF6VG&R֖@BFRVVBf"FF66VW&F7F&Vr'FBW&P&RגFF3( VFW'7FBFRW&f&6RBFV7&WV&VVG2`W"Ɩ6F2&RFW6RFF&6W2E&2"&2`VBW6W"Ɩ6F( VFF66VW&F6WF27V62%G&6@BFvW"FR4&WV&VVG2bW"tFW&2`FV7B6WB7240( &VV&W"FBW6r4Bt22w&VBFVf vrt2'WBFWv( BfFRFV7B6W@7277VW0( 6gGv&RFVfVBV6W&6RWGv&6gGv&R666FW&&ǒ&VGV6R&F6FBW&F67G0gWGW&Rvp&VF7FrFV6wfW"FVזV"W&B2FvW&W027rFRvWfW"rf'v&BB6PbFR7W'&VBG&VG2B&V6W276&RFFV&6R&W@FRgWGW&Rg&vN( 27W'&VFǒ6VVvFFF( 2&WBf'7FǒvFWfW"֖7&V6rFFfVW2FF6VG&PvW"BVW&w67VF&R&VBF7&V6PWVFǒF2vvVW&FRw&VBFVbVBFv66VB&RW6VBFVBW2'WBFF6VG&W2&PvrFfRFFbv2FF6RFRw&VVW6Pv6W2ख7&V6VBf'&R6fW&vRBW&f&6RWGv&2pFF6VG&W2F&R6VB&WGGV6vW&R'WB'W&&V2&R7FBfrFV"VVG2WB6VG&W2F2V2FBFF6VG&W2&RƖVǒF&VvFFRf6GbW&&&V2vWfW"&fVBvfW&V@fW7FVBWGv&g&7G'V7GW&R6VBV&R&RFF6VG&W2F&R6FVB6VW"BW72W&&6VB&V2( 0vWFW"FB&RFRT"V6WvW&RFRv&BगN( 26v'F&VV&W&rFBFRvV"2FR6VBvFF2FW&6V7FfGBv&R76&Rf"PBWfW'RBW7B&vRFF6VG&W2F7Wǒ7&P7F&vRB6WFR66GF6FG'&W&vPFR6RvFRVV7G&6G2&VvBB6Br6FP6vrFF6VG&RfBFBBf6W27&V6pVBbVG&FF6WFFFRgWGW&R( 2ffW&p&R66RF&v6F2BFFR67VW"FR6vrFF6VG&Rv6&R7&V6vǐ6gGv&RFVfVBW'66VBBf'GVvFFP66VFV7b'Ff6FVƖvV6RB6gGv&RFVfV@g&7G'V7GW&RFW&Rv&R76fR&WV&VVG2f"6WFPvW"Bv7&VFRFR'GVGFfRW'66VB@f'GV6WFW"7&VB7&72VFRFF6VG&W2F2v6fRbFR6W77VW2FBVRFFF`2&Vr76&RF&W6fR6Bw26fRF&VF7BFBFPvr7BbFR6vrFF6VG&RBbvW WGv&r67G2vWfVGVǒRFR76&RfW'V676&RF6WfRwwrWGv&6WW&VvR6У3p
